I have revised the code and push the development one step more further. For the moment, the game has no sound, no music and the GUI are in French.
It's a 2D game and I don't really like 2D games. Anyway, I will release the source code with graphics. You need to have PureBasic V4.00 to compile the game.
The game ...
In classic mode : Shoot down as many asteroids as you can. At each level change you will have one more asteroids to shoot down
In Sprint mode : Shoot down 5 asteroids as fast as you can.
Programming Style : Based Object Programming (BOP)
