A nice game, with some pretty good puzzles. I appricate some of the little touches, such as the camera panning to show the door that opened and the effects on a rewind.
I second the point JMS made about rewinding, it's a little thing, but would be nice for QOL. I also would occasionally glitch of the ends of platforms, so you could look into that as well.
Theres tons of room for expansion with additional levels, and other things that your rewind can effect. I'm interested to see what you do with this!
