This was a really fun puzzle game, things were simple and engaging. I liked the pacing and the way levels are designed in the beginning to slowly teach the player how to play. The whole thing was also very very polished. A few things from me, I felt like it would've been nice to be given multiple undos than a single one, and the transitions were a bit too long for my liking; I wanted to jump right back into playing after making a dumb mistake. Overall really solid, good job!
