Yeah, that's a mistake 😔.
I'll upload a fixed version as a seperate file I think.
Lol, sorry for the torture that you went through. I did notice a missconception about the rotation (not your fault, probably mine). You rotate alot when you just tap the button because you're barely moving. You rotate towards the direction of motion, so if you aren't moving alot, then a tiny tap does alot to change your movement. If you're moving more quickly, then inputs have less of an overall effect on your direction. The best strategy is to change directions smoothly, instead of creeping along and changing directions abruptly.
