Thanks for the elaborate feedback! Indeed, during play testing, that was always the tricky part. making clear how the controls work. it always took some explaining, which shouldn't have to be necessary.
The game also stops when you slowed down enough. but when resistance is maxed out, that can indeed be a little while. But A button could have done the trick indeed.
It used to start properly in full screen, maybe I need to change some itch settings, let me check
Thanks!
