Hi,
today I updated the Asteroids project which I posted some time ago. It has
been updated with cool graphics and sound & music. I heavily relies on SDL
and related libs.
The gameplay is very alike Asteroids, maybe except for the “boss” stones 
Some features:
*Antialiased Sprites
*Pixel-precise collision detection
*(Cross) fading using alphablending
Technical:
Because of all the pixel operations (antialiasing), and (on most hardware)
non-accelerated alphablending, all rendering happens onto a software surface
(all images also reside in system memory). After each frame, the software
surface is copied to a hardware double-buffer, which is then flipped, so we
still get synchronized blitting.
