I just wanna say this is actually pretty cool! Unlike some of the more complicated games, you have a very simple rewind mechanic, and designed your entire game around this. I absolutely love it! I have a few nitpicks that I hope you'd take into consideration for your development moving forward:
1) The jumping feels quite floaty - while it doesn't strongly detract from the experience as your game is more puzzle than platforming, I think having a more rigid, better feeling jump will help. There are plenty of tutorials online that describe what I mean by having a better jump.
2) Funny physics bugs - don't mind it too much though. They are typically visual and there are no bugs that have completely destroyed the game yet. The game is quite good if anything!
Other than that, great simple game! I look forward to more from you in the future!
