I did manage to work out a lot of the wonkyness in the physics with this build, while keeping my improved swing controls (and improving the feel of them just a little bit more.) I built a number of levels as well, and added some tricks to the later ones.
I have two more hours to take in feedback and fix problems, so let me know what you think!
