Cool game! I couldn't really get past the third checkpoint though, but I think it's probably because of my slow reflexes; I really wish the jump wouldn't be so high though.
Pretty creative idea though! Also, I got confused: Is the yellow little clock thing good or bad? Are you supposed to avoid it or is it a power-up? I get that it slows time but it also slows you with it, and that made things even harder for me at least. Still pretty cool though! It was fun!
