TEST DRIVE
Three different themes on the racing game : winter, tropical, night
click the image to zoom in
Control :
- movement : LEFT, RIGHT
- speed : UP, DOWN
- stop : SPACE
- theme selection : 1 = winter, 2 = tropical, 3 = night
- quit : ESC
- music,sound off : S
Acknowledgements :
This game would not be possible without

This is really cool
Edit Note that the s3d library will go through many changes before I release it for real. But your program will of course continue to function with the test version of the library that you've used now.
