Yeah, that camera issue is something I couldn't really figure out in time. I cheated my way around it by adding a mouse sensitivity slide in a later update, but that's not really a solution. Thanks for playing!
If I were to guess, there's probably an assumption made somewhere about angle going from 0 to pi or something like that, when in practice, depending on the operation, it may go from 0 to 2*pi or from -pi to pi. That has bit stung me many times!
