Fun game. I thought the layout of the puzzles were pretty good. I liked how you slowly expanded on a few different variants of essentially the same objects, but used differently. It felt like a pretty good balance of challenge for a jam (not so hard that it's difficult to finish, but not so easy that it got boring or repetitive).
Sound and gameplay was pretty good too, though I would have loved to see a controller option (I'm not very good at WASD platformers). Nice game
