Hi the game is getting better every update keep it up. Anyways I just found a bug in your game where if you drive on the side of the wall and the drive up the ramp in the map corner you end up driving on the wall and then driving off the wall and you fall off the map.to fix this you can add invisible barriers around the whole map.if you use you use unity to make this game you could just add walls on all sides of the map that are very high and disable the mesh renderer for all of them 😃
