I haven't quite beat it, but so far most of the puzzles are smart and well-made, and have enjoyed most of them. If I could give one criticism it would be that I feel like this game could benefit from an "undo" mechanic, similar to games such as Baba is You. It would help in some levels where you can easily get yourself killed, and help so you don't have to start the attempt over again. That aside, again, this was really well done :)
