BulletBall is a simple 3D game written in C++, using the Irrlicht Engine, Bullet Physics, and SFML.
The gameplay is not particularly complex - you control a ball around a track using the WASD keys. See the [Screenshots] for more info.
If you are using Linux, you can simply head over to the downloads page to get the latest release.
