Game actualy works, but thats about it
- Instructions should give information on how to drive the car, aka arrow keys ... just because its self explanatory to you (because you made it) doesn't mean it is to everyone
- You should really check to see if the person just did a 360 and crossed the finish line backwards. You could do this by adding checkpoints either along the track, or have it so that if it crosses the second part of the finish line before the first ... instant game over.
- You seem to have the engine worked out ... more tracks would be cool ... also making some type of acceleration and skidding on turns would make the game more interesting.
