Users shall be able to define keys in a settings menu later on. I think that is possible with the Input system plugin, but i have yet to try it out.
It's wasd at the moment because i spilled coffee on my keyboard, and the arrow keys where unfortunatly damaged.
Okay, since two people complained about screen size,i'll make the screen size customizable. Regarding the zoom out depending on car speed I had such a feature on another game of mine, although it lead to a strange error with pasting to the canvas, so I'm afraid to try it again.
