Haha yeah the physics needed another pass. I arrogantly thought I'd ignore the built-in physics engine and just make my own so I had more intuitive controls. Obviously my hubris was punished by the gods of vector math. If I had had more time I would have fixed the character controller and redone the planet gravity interworkings, esp. the mass increase on the planets. Although in the end it's kind of funny when you make every moon smash into a planet.
