Nice look-and-feel, and the implementation is super smooth. I'm super impressed that you did this as a solo project! Implementing this sort of positional stuff in 3D in a way that's logical and usable is a big challenge, and you did a very good job. As with a lot of the platformery entries, though, I have to wonder whether this was the best jam to enter it in--the judging metric doesn't really account for things like how good the physics was.
