It's annoying that some of the walls are not visible and that the collision system doesn't let me jump sometimes when it looks like I should be able to. There's also quite a bit of cheese; there's one level (I think it's the septagon) with a bunch of small platforms next to each other than you can just do with the line and no other shapes. Despite this I think there's potential, and it could be fun if there were perhaps more opportunities to use a certain shape, and a more forgiving platforming (and rotation?) system.
