Take a chance on me

Since this game doesn't follow the theme of the jam at all I decided to add the chance for a flat tire. Every time the player hits another car the dice will be rolled, and there's a 20% chance either the left or right rear tire will blow out. This will cause sparks and it'll be harder to steer the car. Creating an extra challenge to the game.

I fixed some other bugs in this update like adjusting the fire direction when a player crashes into the grass.
