Here's a 3rd capture. The ship is controled on keyboard now. I rewrote completely this part of the code that was a pure non-functionnal hell. Now it's way simpler, and it works.
For now, the idea is to avoid enemies and mines, stuff like that, but if you don't touch the controls, the ship will follow the track, and will never crash against the walls.
This autopilot - thing was more of a compromise, for I really didn't manage to code something that allowed the player to drive freely along the track. So I guess I still have to insert some real racing elements, to make it fun.
Btw, the music is an original one, it was composed on a GameBoy Color by R3Z, a friend of mine, and incidentally owner of www.chiptune.com
