on the first one, i tried to make the music a bit chill because Maria and friends go on vacation. on your second point, well this might sound weird, but in my country cars don't run but they drive, maybe that's just the Netherlands but idk. for reals i get where you are coming from but i just tried to make a very simple endless runner so it was a lot easier to just make these controls than to study cars for a few hours.
anyways, thanks for the feedback and that you played the game! i will now update the game because i accidently left the project name in i used before i started thinking about "hey, wouldn't it be fun if it was in the Marry Maria universe?"
