Very well done. Presentation is excellent, obviously went minimalistic with the art style but it was nice and readable and easy to learn the game without reading a wall of text worth of instructions, and that's what it's all about in a game jam! Music is solid. I don't personally care for these kinds of puzzle games once the levels start getting difficult, so I'm not the right person to judge it for fun or not, but I think this is a great entry to the jam!
