I really Liked the way you used the "rewind", I think it's not so far of what we tried to do on our game.

In my opinion there is a lack in feedbacks (sound or visual effects) but it's pretty amazing that you did all of that by yourself, Good job to you !

 like this concept, games like this benefit from good level design !!!

Really interesting puzzle game and level design

keep it up!!!

Had me stuck in a level, for thinking how to do it. It's a good puzzle game! A little bit of change and need of polishing there but it was great. My biggest concern maybe was the lack of audio in game (like bgm or something that eliminate the silence)

I like this concept, games like this benefit from good level design so I think you need to make improvements there.  Any game would also benefit from music and sound effects. Overall, good job!

Really interesting puzzle game and level design. You should add some BG music to make it more fun. The UI is also good but still need to improve. Overall, it is a decent game. :)
