I liked the game.
Here are some points for improvements:
1-I think the first level should be on a more musical track to help the player become familiar with the controls.
2-Another point is on the intro screen, which is a little difficult to read the information because the background is disturbing the reading.
3-I found the gameplay a little heavy, the steering movement should be smoother so the player can feel both the weight of the acceleration and so he has a better chance of turning the car.
