Don't get me wrong, I love this game. But there might be a 'little' glitch in it; the collisions don't work. The whole time I played, I only got hit by a spike-thing(what have you) once. The rest of the times, I walked(glided? how would you say that?) right through them. It's a fun game, but you need to work on that bug. I hope succeed with your game and have fun doing it :)
