awesome game, very , VERY well polished in all aspects. my little observations:
- you should really try and make the "kill" areas a bit farther. there is speedrun potential in this game, using the gravity to go around areas, but the closeness of the killzones makes it a tad bit harder to try those.
- the before-the-last level seems to have been left out with some unfinished stuff?
however , this was extremely fun to play, and look at too. good job!
