So, I've been struggling with level generation and making the character not either fall through the floor or float away randomly. I might resort to using a pre-existing physics library if I can't get this to work in a couple more evenings.
I'm pretty sure you can work "fall through the floor" and "float away randomly" into some Stephen King reference.
"We all float down here something something"
Nah, I'm not sure that'd work...
