Very nice - loved the aesthetics and choice of atmospheric sounds. The main character has cool design, and the other versions all felt distinctive, although I wasn't quite sure what the water shooting was for.
I will say that the last level is a little confusing, and maybe could have used some kind of mini-map, and the fact that some enemies can wipe out your whole health bar in one go is frustrating, as it can set you back by quite a bit, but overall really promising. The fact that you manages to make those large levels in the time limit is really impressive!
