Pretty good. The mechanics work properly, although the movement is a little too fast (But I bet you meant to do that. It made it ALOT more interesting having to watch how much you press). It was pretty addictive, although the background music was really annoying after a while. My only real issue is with one level, after I died once, even if I didnt move to begin the level again, a passing comet could kill me like, 6 times in a row. Still, mad good job :)
