thanks for playing  nesdori ! :)   
imo there is one possible solution and looks very nice :)

yes, very nice, especially at 12 fps :) the first time I saw that effect i just got paralyzed and missed the next phase completely :)

i've found a solution when trying with reduced speed.  
the effect is really cool :-D, but i don't move the boulder at the bottom-right. is that intended?

i didn't move it either. i assumed that the voodoo below it is just remnant of earlier development phase and that it's intended not to touch it.

that's right. boulder is there just for separate hitchhiker ffly :)

ok! :-)  
  
 shredder : not sure if you already knew the following, but i thought let's just share this finding.  
  
in your cave 'shred 060 cursed bricks' you combine a b&b formation with a bfly vortex, which converts into a crawling-b4. i was wondering if such trick is also possible with fireflies, since f&F is the mirror of B&B and crawling-f4 is the mirror of crawling-b4.  
but: i just found out that it won't work. during the transformation there is one phase in which row- or column-scanning makes a difference. so the condition for mirrored parity is not satisfied.   
in other words: the trick from shred 060 is unique for butterflies! :-)

btw, guess which cave was inspiration to this one ;D   
i've observed this behaviour of fflies and implement it to this cave :)

hmmm... could be 'golden oldie 6' as it contains an upide-down-stairs (like <a href="https://uploads0.wikiart.org/images/m-c-escher/relativity-lattice.jpg)" target="external">https://uploads0.wikiart.org/images/m-c-escher/relativity-lattice.jpg)</a> as well... :-)
