Interesting take on the theme!
I found Q and P to be a bit illogical for controlling the brakes for a single-player game but maybe it would be interesting as a multiplayer game!
Also didn't seem like you could really lose, since flipping upside down just meant you were flipped upside down and had to wait to be unflipped. I think it'd be neat to give the player some more control there!
Regardless, a neat mechanic, interested in seeing how this'll turn out!
