This concept is really fun, though be it slightly banal. I had a lot of fun playing your game, and I think you had a really unique take on the genre. The puzzles weren't very difficult, but they did have me think for some time before I could solve them. My one major issue with it is that I never understood how the checkpoints work. When I made a mistake it was easier just to reset from checkpoint one, than to figure out which checkpoint I should click and how many times.
