This game is awesome. I don't really know how to write this, but I'll try: It looks like the game had gotten everything it needed developed in time: It has great music, good sound, nice graphics, and it's polished as well and has rewind and a pause menu. No aspect was overlooked.
But the most important thing is gameplay, and it nails that as well. The puzzles keep surprising and actually had me thinking, I'd love to see a post jam release with more levels. Fantastic job.
