This game was super satisfying and had me playing it far longer than I intended to! Good job on that end. However, I felt as though the puzzles were a bit too random. For me, this comes mostly from the fact that I can never be too sure what a button does. I have to click on it to see what it does and since there's so many buttons, I can't possibly remember what they all do. My suggestion for this is to have some clue on the buttons like some indicator of what squares they switch up. Other than that though, nice game!
