Thanks for the free link. It took some doing but I did get it working with footage from my gamejam game. I couldn't get it to work with a youtube URL.
I did experience a few crashes, whilst playing but I'm not sure what caused them. The handling of the car is quite difficult. And the camera angle makes it hard to see ahead. Being on a slope at the beginning isn't very beginner-friendly as most people will tend to fall off the stage before getting a grasp of the controls.
It is an interesting experience of chilling out driving with a video in the corner. I think it'd work better as a relaxing game rather than a challenging one.
