Firlefanz - No skybox yet - The game uses 500 GL_POINTS for stars right now. I've played around with a cube skybox but I need to sit down and work out the images. Ya, the rocks could look better, too - I should experiment with some different textures. I also need to come up with some interesting explosions.

Traveler - I've resized the images and they appear to fit a lot better now =)
