which 4 classic caves (bd1-3) have been mixed here? :-D

hmm... one is obvious, one is less obvious but i can still see it without help. for the other two, i'll have to check the classic maps... :d

ahhh, the third was also not so difficult. i also took it into account before consulting the maps, but i excluded it because i falsely thought you'd follow a certain rule for the way you implemented the caves ;)

got it! :d if i'm right, there are two equivalent possibilities for the fourth cave!

exactly! 2 caves from the same game. :-)  
  
for the others a hint: don't look at the map alone! :-D

my memory served me wrong and i thought that there's only one cave with the "fourth feature" but indeed there's two :)

the solution: this cave is a mix of 4 classic caves:  
  
map structure is from 1-f, random-fill from 2-c (level 1), cave settings from 1-b (level 1) and colours from 3-e (or 3-m). :-)

that was my solution too :d   
  
funnily, i first had bd1-b for the wrong reason. because of the firefly above the start, i thought this was the bd1-b firefly but it wasn't at the exact same position so i thought that perhaps you shifted the random fill. then i noted that the complete random fill is bd2-c, so bd1-b was out of my mind. then when i took a look at the settings, i finally noted that bd1-b was one of the four caves anyway :d
