profi boulder 2, cave i, with an escape challenge!

darkstoorm, me neither, but i've heard good things of them, so i thought it'd be worth the effort to search them through for interesting caves :)

Oh wow, they actually are all in gdash too, mixed with other games too, not sure they are related, e.g. "Brutalo_Boulder", "Gerd_Boulder" (we have those here), "Null_Bock", and "Rockford_"a-j.

I knew I saw this name somewhere :D haven't played the caves though, so it will be fun

while uploading so many no1 caves, i thought some alternation could be a good thing. and i couldn't find a single profi boulder cave in the database although this traditional game series has no less than 119 games! so now i'm going to upload them all!
...
...
or at least i pick out some caves which look especially interesting to me. the series has a lot of challenging caves, which i think is a good contrast to no1's mostly very playable caves.

this one is profi boulder 2, cave b.

the back to back message "placing rocks in the dirt" and "placing dirt in the rocks" may seem nonsensical, but they are actually messages that occur when generating a world in "terraria". it populates the dirt with stone, then softens the distribution of stone by overlaying it with dirt.

speaking of which, the prior cave "rocks in the dirt" uses dirt as initial fill, whereas this one "dirt in the rocks" uses boulder as initial fill.

this was intentional ;)

hi and welcome! :d

first 4* my bad

funnily enough, I know only boulderhead and the first 5 no1's through the 15-game suite.

original cave: bd11 intermission 4

different from original: 2/10
only visual and scoring changes.

aaaaand... that's it for don pedro's remakes! the changes no1 made here were by far the biggest, while the remaining games (j-o) have usually only slight adaptations.

original cave: bd11 cave p

different from original: 6/10
the original is basically releasing three ΖΖΖ by snapping and fleeing while they chase Κ closely. now, we still have ΖΖΖ in narrow spaces, but they're more controllable. on the other hand, the Ν now being inside the labyrinth means that a kind of escape challenge is added at the start.

original cave: bd11 cave o

different from original: 5/10
there are several medium changes that add up:
| visual change
| random ΒΒΒ density drastically reduced, which makes the cave much easier to explore;
| the middle ΛΛΛ was moved and is now much easier accessible (in the original, it seems easiest to ignore that ΛΛΛ completely, but in no1's version, it's practically required for enough ΑΑΑ);
| the requirement is reduced (but due to the density, there are also fewer ΒΒΒ to convert!)
| and the ΛΛΛ timer is hugely increased, making the transformations much less hectic.

still, i think none of these changes is so huge that a higher rating would be appropriate.

original cave: bd11 cave n

different from original: 2/10
only new colors and scoring.

original cave: bd11 cave m

different from original: 5/10
the new space around the ΗΗΗ considerably changes the escape challenge at the start, also Κ now releases all the ΗΗΗ together instead of snapping them free one by one.

aaaaaaand... uniqueness confirmed! :d

ok, let's see about it, solution visible!

that sounds good, then i'm looking forward to seeing your completely unintended solution :d

this time i believe my solution is the intended. after doing logic reductions (and verbal reductions from dustin's comments :) there's basically just one solution option left.

the unintended solutions of the original no longer work, so now, hopefully, the intended solution is the only one! :d

original cave: bd11 intermission 3

different from original: 8/10
the original looks completely insane to me. no1's version is now way more playable!

original cave: bd11 cave l

different from original: 6/10
the left side is totally changed, so that Κ no longer has to make a blast to have enough ΖΖΖ. also, most of the ΖΖΖ are now together, which might turn out to be difficult to handle. on the other hand, these ΖΖΖ were harder to release in original.

original cave: bd11 cave k

different from original: 5/10
no1 has changed the location of the ΛΛΛ inside the normal ΔΔΔ while keeping the basic idea to kind of troll Κ ;)

original cave: bd11 cave j

different from original: 7/10
while the original includes a creative new idea with a vertical(!) ΛΛΛ which has to be crushed to make it usable, no1 version is just a standard explosion cave.

original cave: bd11 cave i

different from original: 4/10
with less ΒΒΒ, the cave has become considerably easier.

however, if you make a upper measure so you can pre-fill the bowl and then drop them in using layers of slime, it *shouldn't* be as unfair!

The concept is not new (see 22 3F "another refill!" and 3F.2 "Make it a smoothie!"), but this is one of these puzzles where the bin is open and you're pushing a light from right to left, as opposed to a standard from left to right.

As for filling gaps, you'd need to be very careful about how you designate them. I find using exactly enough butterflies to make the requisite \s to be too problematic and uncontrollable to be doable.

that's a very cute little idea! i mean, i've seen caves where ΑΑΑ are needed to fill such a basket, but these ΑΑΑ coming from ΗΗΗ is new to me. and the idea has potential to become very challenging if all ΑΑΑ are needed to fill the basket :d

fill the basket!

original cave: bd11 intermission 2

different from original: 5/10
there are several small/medium changes which in sum lead me to this middle rating:
| space was added around the ΖΖΖΗΗ, such that they're easier to release, but on the other hand, they can now only be released together.
| the Θ has more growing space, making it slightly easier to fulfill the requirement.
| the Θ time is reduced, effectively giving more time for the cave.
| and, last but not least, the striking visual difference.

original cave: bd11 cave h

different from original: 6/10
no1 removed two out of three ΖΖΖ colums, massively simplifying the whole thing.

original cave: bd11 cave g

different from original: 7/10
other than in original, the Λ is now necessary to reach the requirement because the ΘΘΘ is usually too fast for other solutions (unless i overlook something). this requires Κ to have the idea that there is a Λ in the cave in the first place!

original cave: bd11 cave f

different from original: 8/10
two major changes were made by no1:
| removing half of the ΖΖΖ at the start
| removing a Δ, which removes the additional challenge to prepare and perform a blast in narrow space and with a lot of annoying ΖΖΖ in the way.

original cave: bd11 cave e

different from original: 6/10
in the original, a lot of ΖΖΖ have to be snapped free and then let them chase Κ closely. these dangers are now almost completely eliminated, although the ΖΖΖ can still catch Κ in a dead-end if he isn't careful.

original cave: bd11 intermission 1

different from original: 5/10
the ΗΗΗ and ΒΒΒ have been arranged totally differently, with several effects:
| the ΗΗΗ no longer have to be released by snapping.
| in the original, the ΗΗΗ explosions can be done more systematically.
| in the original, the ΗΗΗ are released in portions, here they're almost all connected.

original cave: bd11 cave d

different from original: 7/10
no1 added the whole random fill (ΒΒΒ + empty space), with two main effects:
| the escape challenge at the start is now trivial.
| in the original, Κ has to be very efficient with only two ΒΒ available, which is obviously no longer the case.
all in all, the cave is now a pretty standard ΗΗΗ-ΒΒΒ-have-fun cave :d

original cave: bd11 cave c

different from original: 3/10
beside the visual change, there are now two bonus ΑΑ while the original required all possible ΑΑΑ.

original cave: bd11 cave b

different from original: 5/10
there are two considerable changes:
| the ΖΖΖΖΖ and ΒΒΒΒΒ have been moved, such that the ΖΖΖ can be released without snapping. on the other hand, they can now only be released together and they also have become more numerous, so that they tend to annoy Κ more while he tries to blast the ΔΔΔΔΔ.
| the requirement is reduced, making less explosions necessary.

caves with changes: 20/20
don pedro's final game!

about this cave:
original cave: bd11 cave a

different from original: 3/10
no1 adds 10 seconds to the timer, which makes a tangible difference because the timer is relatively tight.

ok, i actually overlooked something quite simple - the way how the Η is exploded by the top-left Β. should be easy to fix with a voodoo, though. prepare yourselves for level 2...! :d

ok, guess it's time, there haven't been any new attempts the last few days. now i'm curious if the intended solution is among yours, and if i can fix the whole thingy ;)

ok :d on second thought, i think i intentionally kept this extra option because i didn't see a way to make use of it anyway :d

dustin, no pushes :)

nesdori, darkstoor, are you pushing the top-left and/or top-right Β in your solutions? 'cause the intended solution doesn't, and i just noted the unintended possibility to blast two ΑΑΑ jails at once with pushes. in that case, the cave could be simply fixed with heavy ΟΟ :d

nesdori: ok, i'll see if i can fix that once the demos are revealed.

my solution uses a cso trick for speedrun purposes but the cave can be also solved without using any cso tricks.

here comes the cso puzzle for april! :d

this is one of the harder ones, i guess, including some plausible but not working approaches and open border effects. it took me quite a while until the final version was ready, and i hope that the intended solution stays the only possible one. i'm curious! :d

that looks cool!

original cave: don pedro bd10 intermission 4

different from original: 7/10
the original has two challenges which were removed by no1:
| another Δ blocking the way to the ΑΑΑ
| only two ΖΖ available so Κ mustn't waste any.

original cave: don pedro bd10 cave p

different from original: 7/10
in the original, Κ is trapped together with the Θ because there are additional blocking ΔΔ. this adds an escape challenge requiring timed explosions. here, without this extra challenge, the cave is a lot easier.

original cave: don pedro bd10 cave o

different from original: 7/10
in the original, the short ΘΘΘ time seems to make it impossible to crush the ΖΖΖ with the ΘΘΘ; instead, it seems to be better to trap the Θ for enough ΑΑΑ. no1 lowered the ΒΒΒ density which makes it a lot harder, if not impossible, to trap the Θ; on the other hand, he increased the Θ timer so now it's possible, and surely simplest, to lead the ΖΖΖ to the Θ. so the best solution method has changed completely.

original cave: don pedro bd10 cave n

different from original: 5/10
there are basically two clear simplifications:
Α the requirement is reduced from 60 to 40. especially if Κ works with "semi-efficient" ways to crush the ΗΗΗ, this can make quite a difference.
Α the pieces of empty space are new and make it easier to release and escape the ΗΗ, especially in that narrow space.

original cave: don pedro bd10 cave m

different from original: 5/10
the ΗΗΗ are re-positioned, and their release is now much less dangerous for Κ.

original cave: don pedro bd10 intermission 3

different from original: 8/10
no1 has changed the random seed, removing a very tricky escape challenge at the start. on the other hand, no1 took more than 20secs away from the timer, considerably increasing the time pressure on Κ.

original cave: don pedro bd10 cave l

different from original: 8/10
among other changes, there are two bigger ones:
| the Ν is no longer inside the cave border. this makes the original very unique because it plays with a bd1 engine bug and adds an extra puzzle element to the cave. with this extra feature removed, the cave looks now pretty standard. so this is the main reason for my high rating.
| also, as usual, no1 gave the bottom-left Ζ some space to move. in the original, chances are 50/50 that when Κ frees that Ζ, it will follow him without gap and then crush him at the corner.

original cave: don pedro bd10 cave k

different from original: 7/10
two difficulties have been removed or hugely simplified:
Α in the original, there's another Ζ at the end of the stairs, forcing Κ to release it then run upwards being chased;
Α the explosion challenge at the right side has been changed by removing a ΔΔΔ, adding two ΖΖ and reducing the requirement, so that some ΑΑΑ can now get destroyed in explosions without ruining the solution.

original cave: don pedro bd10 cave j

different from original: 9/10
the original is maybe the most inventive and challenging puzzle cave of don pedro's entire work. with no1's changes, it's now a mere standard explosion cave.

Yes, the original don pedro!

altermaven, are you referring to the original version by don pedro, with less time? yeah, that's true. that's why in the original cave "don pedro bd10 cave i", i increased the timer to make it playable here at this site.

This cave is impossible on ntsc because of the timer differences!

original cave: don pedro bd10 cave i

different from original: 6/10
no1 increased the timer, thereby hugely relaxing the speedrun cave.

"april showers"

a race between kites based on dancing fly formations (dff)!

from left to right:

flying kite
based on the dff "lifted Ζ-vortex" (episode 6 in Arno's forum thread)
speed: 5 frames per step

soaring kite ("fast" version, relatively speaking - still very slow) :d
based on the dff "one busy bee" (episode 22, coming soon!)
speed: 17 frames per step

soaring kite (slow version)
based on the dff: "three busy bees" (episode 19)
speed: 25 frames per step

if you solve this the intended way, Κ gets exactly the required amount of ΑΑΑ!

original cave: don pedro bd10 intermission 2

different from original: 6/10
other than in the original, this version works "semi-automatic": Κ can wait until the ΘΘΘ kills a Η and converts, and then, while avoiding the remaining flies, Κ grabs just enough ΑΑΑ (at least this worked for me on several testing attempts). in the original, Κ has to release the ΗΗΗΗ himself and lead them to the Θ /the Θ alone wouldn't give him enough ΑΑΑ).

original cave: don pedro bd10 cave h

different from original: 8/10
in the original, it's necessary to blast the way free between the ΒΒΒΒ and the ΛΛΛ. instead of this, no1 added a little "escape the room" challenge at th start.

original cave: don pedro bd10 cave g

different from original: 7/10
no1 swapped the Ν and Ξ and changed all don pedro's diagonal ΔΔΔ lines into ΒΒΒ. as a result, Κ no longer needs to blast his way through the cave, and also the (re-)trapping of the ΘΘΘ can be a lot simpler if done cleverly.

original cave: don pedro bd10 cave f

different from original: 5/10
again, no1 removed some ΖΖΖ - the ΓΓΓ line is an overwritten line of ΖΖΖ.

original cave: don pedro bd10 cave e

different from original: 5/10
no1 removed a lot of ΖΖΖ in the middle room.

200Α run free! :d

forgot to mention that of course the final bonus challenge, worth 10Α, is supposed to be the hardest. hadrig would probably have mentioned that ;)

after Κ has solved his second exercise from professor gumblegore, he finds a giant mansion in the middle of nowhere. even the entrance door is five times his own size! Κ wonders who might live here. it must be a big, biiiiiig creature. as if to answer his unspoken question, a big, biiiiig creature approaches him.

"hi! how're yeh doin'? i'm professor hadrig. i'm a double-giant."

"ehm... hello, professor. i-"

"jus' call me hadrig. everyone does that."

"o- ok, mr. hadrig-"

"jus' hadrig."

"o-ok, hadrig. i- do i have to go into your... villa... to move on?"

"villa? ha ha." the double-giant chuckled. "that's jus' ma tiny little hut."

"hut. i see."

"looks cute, dunnit?"

Κ thought about what to say. he had many adjectives to describe this monstrous building, but 'cute' wouldn't be his first choice.

"it's... well, a bit dark, but... nice. definitely."

"yeah, ma little brother says that too. he thinks i should buy some fireplaces for it." he shrugs his shoulders. "but i like it as it is."

"i- i guess you have a puzzle prepared for me to solve, like professor mc donadall and professor gumblegore?" Κ wanted to change the topic.

"yeah. more than one, actually. they're inside. yeh can get 200Α!"

Κ's eyes widened. "wow!"

"but i don' think you can get'em all. especially my name puzzle is difficult if yeh wan' everythin'. that's why i require only 180Α to exit my hut again."

of course, that only motivates Κ to prove the opposite. he always loved challenges. "well, we will see!", he says to the double-giant.

"alrigh' then, good luck! some motivatin' music will play once you're in. i luv music."

"thank you." hadrig doesn't move out of the way, but Κ simply walks past him between his legs. with a determined expression, he slowly opens the colossal door...

@Rob Gilbert, cheeky :D

original cave: don pedro bd10 intermission 1

different from original: 3/10
no1 added all the empty space. the original solution - "walking up the stairs" - is unaffected and i think it's still the most apparent way to solve the cave. however, since the ΖΖΖ are connected now, some Κs will have different ideas including the release of one of the ΖΖΖ groups.

original cave: don pedro bd10 cave d

different from original: 3/10
there are several minor changes adding up to this rating:
Α color change
Α change of random seed
Α no1 added a few custom extra ΑΑΑ
Α slight decrease of the Α requirement (74 to 70, probably just because it's a round number, no1 likes that) ;)

original cave: don pedro bd10 cave c

different from original: 1/10
only scoring changed.

original cave: don pedro bd10 cave b

different from original: 7/10
the original is a tricky explosion cave in narrow space. now, with the ΔΔΔ shortened, explosions can still be used for bonus ΑΑΑ, but they aren't necessary anymore for the requirement. the overall narrowness of the cave is still there, though, so avoiding all the ΖΖΖ can be a little bit tricky.

caves with changes: 20/20

note that boulder dash ix has not been remade by no1!

about this cave:
based on: don pedro bd10 cave a
different from original: 4/10
no1 increased the ΘΘΘ timer. in the original, Κ has to rush quite a bit to trap the ΘΘΘ before it grows too big, this is now considerably relaxed.

p.s.: wow, four 8/10 caves in the last few caves! before that, there were only two 8/10, one 9/10 and one 10/10 in the whole series! :d

original cave: don pedro bd08 intermission 4

different from original: 8/10
the original featured two very unusual explosions which, to my knowledge, haven't been seen in that form in any previous fancaves. these explosions are no longer necessary here. instead, Κ has to move the lower ΒΒΒΒ out of the way to get enough ΑΑΑ. (this is not true for this version at this site, where the ΛΛΛ bug doesn't exist so Κ can get enough ΑΑΑ without pushing.)

original cave: don pedro bd08 cave p

different from original: 6/10
there are two big differences from the original, which simplify the gameplay considerably:
Α in the original, the ΖΖΖΖ have to be snapped free under quite dangerous conditions.
Α in the original, all Α are required, which makes a "pixel-perfect" extra explosion necessary.
however, in comparison to the previous three caves (which are all rated 8/10), the basic character of this cave remains unchanged (basically an explosion cave).

original cave: don pedro bd08 cave o

different from original: 8/10
also this cave plays a lot different from don pedro's original:
| original: blasting your way through a 3-size ΔΔΔ
| no1 version: a kind of bd2-int1-ish cave where Κ has to somehow move the entire "building" in a way that the Ξ does not get destroyed (here at this site, with indestructible Ξ, the cave is basically very easy.)

ah, of course! the ΒΒΒ cannot fall sideways with just 1 gap in-between, that's why they accumulate and make it possible for Κ to sneak through from the right half to the left half. nice!

but nesdori, your longer solution is also cool :d

ok, showtime! :d

ah, so now we have all ΑΑΑ in 8 secs. that's interesting :D

:)

btw it's 20Α in 9 sec, not 21Α in 109sec ;)

heywood: :d

nesdori: well i had a 20Α solution very quickly, after roughly 5 attempts, but that solution is nowhere near a full ΑΑΑ run. it was a result of quick trial-and-erroring.maybe i just got "lucky" to find a working way so quickly, and the cave deserves a higher rating. in any case, my solution is not very hard to perform once you know what you're doing.

anyway, i'm definitely curious for the unlocking! :d

i think getting all 27 is probably a 5/10, but doing so without being entombed forever warrants a higher rating. :)

dustin, well the answer is: all 27Α are possible :)

the required number of ΑΑΑ and your estimated difficulty level is quite surprising. i would say that getting 20Α is more difficult than 5/10 compared to the previous cave ratings. and in many cases, if you can get 20Α, you are on the track of getting almost all if not all ΑΑΑ. i'm really curious about your intended 20Α solution with just 5/10 effort :)

(based on no1 16 bd game g cave n)
if i remember right, this is the first cave of the series based on a fanmade cave!

this is basically the situation after Κ deflected the ΖΖΖ and then does nothing until the ΘΘΘ converts into ΒΒΒ (an unlikely but possible scenario). i wonder how many ΑΑΑ are possible now!

difficulty: 5/10

original cave: don pedro bd08 cave n

different from original: 8/10
the changed placement of the ΗΗΗΗΗ row subtracts and adds a lot of ideas here!
| in the original, we have basically a ΗΗΗ-ΘΘΘ explosion cave with speedrun elements because of the short ΘΘΘ timer.
| the speedrun is now cancelled because the ΗΗΗ are already in place. however, a new interesting effect, whether intended or not, can be seen here: if Κ does nothing, the ΘΘΘ may convert either into ΑΑΑ (likely) or ΒΒΒ (unlikely). in the latter case, the ΘΘΘ is trapped into exactly 200 pieces, so we see a trapped ΘΘΘ converting into ΒΒΒ because it's just overgrown!
the reason for this randomness is that if the leftmost and rightmost ΗΗ are hit directly by the ΘΘΘ, they generate three more ΑΑΑ than if the ΘΘΘ hits the second-left or second-right Η.so the total growing space for the ΘΘΘ can be 196, 198 or 200 pieces.

nesdori, it was because of this very obviousness that i was wondering how long you would need to find it ;)

so obvious but at the same time an obvious blind spot :)

after checking all the demos in the original, i noticed that even one more Π can be converted! :d

original cave: don pedro bd08 cave m

different from original: 8/10
the original is a kind of "fake ΗΗΗ-ΘΘΘ-cave" because the Θ converts immediately at the first explosion. now, with the shorter Θ timer, it's kind of the opposite: Κ should wait for the Θ to grow out and it will soon convert into a lot of ΒΒΒΒΒΒΒΒΒΒ. also there's a new "fake solution" - if Κ just traps the ΘΘΘ, he will be a few ΑΑΑ short. all in all, i think the cave plays a lot different from the original.

original cave: don pedro bd08 intermission 3

different from original: 4/10
among other changes, a Β is added next to the wall, which makes it unnecessary to push the other Β there, so it effectively gains time, which can make the difference because time is relatively tight in original cave.

original cave: don pedro bd08 cave l

different from original: 7/10
the most striking change is the new long row of ΖΖΖΖΖΖΖ which changes a lot:
| rockford no longer has to push all the ΒΒΒ aside at the left.
| rockford has enough ΖΖΖΖ for explosion, in the original there are only two ΖΖ for two explosions, one of which has to be lead to the explosion spot from afar and by snapping.
| on the other hand, of course, more ΖΖΖΖΖ make the cave also more dangerous.
furthermore, the access to the Ξ has been made easier by changing a ΕΕΕ into ΔΔΔ.
all in all, the gameplay is very different from original!

(also the colors are changed.)

original cave: don pedro bd08 cave k

different from original: 1/10
only the requirement was changed (which doesn't matter because all ΑΑΑ are together) and scoring.

original cave: don pedro bd08 cave j

different from original: 1/10
only scoring changed.

original cave: don pedro bd08 cave i

different from original: 3/10
only the timer is increased by 20 seconds, so there's slightly less time pressure.

original cave: don pedro bd08 intermission 2

different from original: 6/10
in the original, the ΘΘΘ conversion has to be timed very well, such that Κ gets enough ΑΑΑ and also has enough time left to collect them. in no1's version, the ΘΘΘ times is heavily reduced, giving Κ effectively more time, such that this challenge is far more relaxed.

original cave: don pedro bd08 cave h

different from original: 5/10
the ΘΘΘ/ΛΛΛ timer was heavily increased, which makes it a lot less time-troubling for Κ to convert the Θ and then break the Δ. in addition to that, the colors have remarkably changed.

original cave: don pedro bd08 cave g

different from original: 5/10
the extra column of ΓΓΓ at the right makes it more likely that the ΖΖΖΖΖΖΖ get killed automatically by the ΘΘΘ, making it easy to exit at the end.also, the increased timer is helpful, the original can be tight. finally, the cage of the left Θ is shortened.

original cave: don pedro bd08 cave f

different from original: 7/10
also here, several changes were made at different places.
my main reason for the high rating is that three more or less difficult explosions at the right side, leading to the Ξ, are no longer necessary.
also, the way to the eight ΑΑΑΑΑΑΑΑ at the left side is now a lot easier because a Β is added next to the ΔΔΔ and a lot of ΖΖΖΖΖΖ are removed.
the colors are also different, plus a few more small changes.

original cave: don pedro bd08 cave e

different from original: 5/10
there are several small changes. imo the most effective change is that the ΖΖΖΖΖΖΖ at the top-right are surrounded by ΒΒΒΒΒΒ. with this, there are far fewer ΖΖΖ bothering Κ throughout the cave.
another change is that the Θ is no longer "pre-trapped", which means it is most likely converted by the ΛΛΛ now.
also the colors were changed.

original cave: don pedro bd08 intermission 1

different from original: 2/10
slightly different colors and more bonus points.

original cave: don pedro bd08 cave d

different from original: 3/10
Basically, the random seed is different, probably because there is a Η in the Ν area in the original. also, the ΕΕΕ color is changed.

original cave: don pedro bd08 cave c

different from original: 1/10
only scoring changed.

original cave: don pedro bd08 cave b

different from original: 6/10
in the original, the Θ is initially blocking Κ and often gets destroyed by one or two ΖΖ, then leaving Κ with the challenge to deal with the remaining ΖΖΖΖΖΖΖ. in no1's version, the Θ "autokills" many more ΖΖΖΖ before converting into ΒΒΒΒ, so Κ has to deal with much fewer ΖΖΖ afterwards, which he can often kill himself. that's quite a huge simplification.
(also, the requirement is reduced from all 6Α to 2Α.)

about this cave:

original cave: don pedro bd08 cave a

different from original: 3/10
the timer is increased from 50 to 60, slightly relaxing the speedrun. (also, this is another case where no1 added bonus score although there are no bonus ΑΑΑ) :d

nesdori: and the answer iiiiiiiis... yes! :d
after checking your solutions and combining it with mine (which is different), i saw a 12Α solution fairly easily!

i won't reveal my solution yet, trying to make level 2 as hard as possible ;)

still just two different solutions after mine solution :) but nice solution Arno! i was looking for alternative solutions but i missed your solution. now i really wonder if even 12 is somehow possible..

ah cool, at least 2 different solutions! ;-D

Arno: the main reason why i did not include extra ΠΠΠ was that they might be abused for a solution where the extra Π is not converted but helps convert the others!

I'm also curious, but I guess it's just how fast "the only" solution is executed :D double pushes might also come in handy

At least you haven't made extra boulders for bonus score available, so i guess you were pretty sure that isn't possible? ;-)

thanks Arno! :d i'm curious about that too, especially because i needed a while to figure out a solution for this version, and i was a bit surprised to see relatively many solutions in short time!

Nice one! I'm curious if this rockoban puzzle has more than one solution! :-D
