Good game concept. It just gets repetitive pretty fast and there is no scoring system. it could be cool (if you have time) to do separate levels that you need to go through maybe some levels could have cars wanting to turn left or right to stop the repetitiveness. You could also add some sound effects such as car horns beeping when the line of cars gets too long to add to immersion. Just some suggestions, I enjoyed playing it. Good job and Good luck
