Nice music and good concept! I like how the patterns are (I assume) procedurally generated. The butterfly movement was a bit to jittery for me. Smoothing out the motion might make the experience more relaxing.

Got the game running after fixing my own error.  I have to say it was a quite relaxing experience collecting butterflies.  Also, the butterfly generation made a variety of interesting creations.  Additionally, the music complemented the mood of the game nicely.

I seem to get an error on Windows 10 with the message:

  File "./main.py", line 645
    iterationCount += 1
                 ^
IndentationError: expected an indented block

I encountered a few errors:

• print statements lacked parentheses. running 2to3 -w main.py fixed this.

• the music file in your itch.io package looks for ABMusic.mp3 but the file is named abmusic.mp3

• I believe you should call pygame.mixer.init() right after pygame.init() in the initializeDisplay function
