This is a cute game. I like the sprites for the moth and the other small characters. The weightlifting pupa is funny. The cocoon/shooting mechanic works pretty well I think. The music is good too.
I also found it a bit difficult to make progress. My main suggestion would be to perhaps add checkpoints at some screens so that you don't have to start over from the beginning each time, although maybe that would make it too easy? Also, it seems the 'Wake again' button at the end doesn't work for me (playing on the windows version), but I expect that would just restart the game, so it doesn't really matter.
