Wow! This is a really impressive and original game. I love the art style and music. The game play is interesting and compelling. There's tons of variety. It's a great game.
The only thing I could complain about (and only in a minor way, because I'm probably the problem :-)) is the controls: they just don't feel intuitive to me, and half the times I take damage it's because I knew what I wanted to do, but pressed the wrong mouse button. I don't really know how to improve it though. Arrow keys would feel more intuitive, but that would be super challenging to implement because which way is up/down or left/right changes depending on where you are on the revolution...
Anyway, congrats on such a wonderful finish!
