This is weirdly cool in a way. Hilarious intro - love it. Other things of particular note:
1) Excellent sound design. Every hit with the patience balls, with the walls just has that OOMF. Very cool.
2) Good art direction. In conjunction with the sound design, your choice of sound, music and art style all fits quite cohesively. Was a pleasant to play from start to finish.
Thematically, I admittedly have no idea what to feel about it. You have implemented it both narratively and mechanically a good incentive for the rewind but I also don't feel particularly satisfied with how it works. I think it's the fact that you have to replay the level everytime? While sure, it a way that DOES test your patience but it just goes against the nature of having a fun game?
I might be rambling on that previous paragraph. So if you are interested in gathering more feedback after this game jam, consider asking what people think of your rewind mechanic. I'm actually at a loss and I don't really know.
Very fun game actually, for how short it is. Too bad I got a cat, I simply was too impatient I guess. :[
