I really dig the core mechanic of the puzzles here; how does this not have more ratings? I'm very impressed with the quantity and challenge of the puzzles you came up with in only 48 hours, though I'd love to see more. A great feature to add to this would be an undo button to reverse the last move from the player. Would definitely make mistakes less tedious, and hard levels more fun. Overall, this was fantastic, and I hope you continue to develop this game.
