I like the idea of making a game about the butterfly effect, but when i started to play i thought that you first play a butterfly and do something and then play someone else and do something else and so on and so on and in the end it leads to a big event. This gameplay is okay, but i difficult, i couldn't get past level 3. It's cool that you tried out this idea tho, that's what Game Jams are for. The music gets annoying pretty quickly, but the graphics are amazing. I noticed that some of the sprites don't really fit together, some have an outline, others don't, and the butterfly looks alot different than the other things.
I hope the feedback helped you a bit, it would be cool if you could check out my submisssion too. Thanks! :)
