Really nice game! The controls feel good and the artwork also looks very nice.
The shooting mechanic can just be skipped and run through the level avoiding the enemies, maybe adding some way to force the player into using the shoot-rewind tech would be nice. The background also leaves a black void at the top and bottom of the level, but that might be intended and didn't feel bad at all, so no problem.
But apart from that, the game has a simple idea and manages to build nice levels around it. Everything feels like a part of the same game and I had a good time playing it. Good job and keep it up!
I would really appreciate if you could check out my game and leave a rating, thanks :)
