Hitboxes are a bit off to the point you may hit something when you clearly don't on screen. Sometimes you hit an object and instead of getting a fail screen, you are just stuck and have to reload the game. I like the art but a suggestion I'd give is to be consistent with the pixel size of your art. Both the car and the gas station pixel sizes match each other but they do not match the pixel size of the brick wall obstacle (as well as the traffic cone, or walls)
