The ability to reverse time was a neat mechanic to play around with though I wish the reverse had the same hold feature as the movement where if you held the spacebar down it would continuously rewind, but that's just me.
The puzzles themselves were decently made and the last one had me scratching my head a bit. I do wish though that the rewind mechanics was explained or how to use it cause I had to start pressing random keys to find it.
Also one of the smoothest transitions between levels I've seen. Really loved it.
