Thanks for playing!
Ah yes, I did not take different resolutions into consideration - a massive oversight!
The spin is actually intentional but maybe it is too harsh, some angular damping would is a good idea!
You can control rotation in air with Q/E but it only appears on one sign somewhere where you are likely blasting by very quickly, so perhaps a better tutorial would make that more clear. That being said, the rotation being on separate keys does feel a tad clunky - I had it attached to the forward/backward movement keys before, but that led to a lot of unintentional nosedives off of ramps.
