 - allow stopping car rotation in air like in Trackmania
+- prevent time overflow! stop incrementing level frame once it's at maximum
 - car shadow? probably would have to be done as screen space effect with
   z-buffer (shadow as 3D model would require collision detection and would make
   renderer depend on physics engine). Maybe like this:
