After doing this I started adding features to the game such as a speed multiplier that changed the speed of the car and the speed of movement from side to side. This was altered by the use of checkpoints throughout the level. Every time the player passed a checkpoint then the speed would be increased. This made the game much more appealing and also slightly challenging. Anyway here is the video:
The next main part is to parse the file calculating the scores and then inserting the new score at the right point. I also need to output the high scores table to the screen. It does seem that by adding a high scores system I am edging closer and closer to having to create a proper front end :)
