holy cow, I can see why this got removed.
try practicing a little more before you upload something to a game jam, ok?
I'm not an expert on game development, and I'm certainly not a very good critic, but I'd say that it just doesn't feel right. It just feels like it was made very sloppily. That's really all I can say about it. I'm glad to hear you've practiced, though! Try making a remastered edition, and maybe with better methods of doing the rewind and physics effects.
