Like every comment has said so far: Amazing Game! Well Done!
The art is great, the music sounds amazing, the sound effects are good, the only thing I can really criticize is the fact that it wasn't really clear to me what was dangerous and what wasn't, what could 'hurt' me and what couldn't, where I could stand and where I couldn't. The more I played the game, the clearer it got, but I would've liked to have known it from the start.
But other than that (very small) citique, I thought this was a brilliant game!
(I'd be very surprised if you didn't win, although I haven't played that many games yet so I maybe shouldn't make that judgement yet)
