like the level the car move smoothly and that the music bring the game together as this fit well with the timer event and that when you have resented that you keep with the time as this add bit of a diffulcuy to the game as you are having to try to finish without making any mistake.
improvement could use something on the side of track so some building so there are something to the environment and the car could need a texture so race colour to it so it look like more of a race car.
other then that great start
