I really like this game. The puzzles are interesting and everything looks stunning. Great job! I try to always give some feedback in the comments, but I don't know what I would change here.
Maybe it would we nice if the rewinding was sped up a tiny bit, to prevent people from waiting for too long.
I'd really appreciate it if you would have a look at my game as well. It's actually quite similar to your game in some ways. Be sure to download the smaller version :D
