This was fun! I like puzzles and it was fun figuring the level out. I kept thinking after I died that I would soft lock and be stuck, but I found it very impressive that there was always a way to progress no matter where I restarted. I also like the interpretation of the theme to make a game with one button. At first I wondered what the squares were for, I thought they were only checkpoints, but then at the end I saw them all line up and I thought it was very clever :)
