My opinion about your game is that I never really feel the need to rewind time. There are some collision problems as well. A bit more focus on level design could improve even more your game. But hey, it was fun to play, non the less.
If you have some spare time, check my puzzle game. The main mechanic is time rewind of your bomb, but enemies react to your bomb is different ways. There are 12 levels and you can do they in any order you like. I'd appreciate any rating https://itch.io/jam/brackeys-4/rate/721302
