Great idea! I love the idea and the execution of it. The puzzles are really fun, although many of them are susceptible to moves that simply repeat many times and bypass parts of the puzzle that are (I think) meant to be interacted with. I would recommend having a turn timer, collectibles, or some other way of encouraging players to interact with the levels in a more thoughtful way to complete the game. Perhaps some mechanics that complement the looping and loop as well would be good, such as blocks that turn on and off every move in later levels. However, the game is still fun and requires a good bit of thought to figure out the puzzles. Great job!
