Just the right level of frustrating to where it made me want to solve the problem laid out in front of me. Super simple art, but in a good way that let the puzzles be the main focus. There's just the right level of juice and it felt good to reach the goal and it felt right when I'd hit a block or couldn't move further. I wish I had some constructive criticism, but really this is like an ideal jam game. Smart concept, great take on the theme, and excellent execution. Really great job!
