A 3D game demo featuring Sonic the Hedgehog. More than anything it's been a way to learn about building a 3D game from the ground up, so rather than use libraries I tried writing my own physics, key frame and bone animation system and sphere-mesh collision to enable Sonic to walk on arbitrary surfaces. I then began writing a level editor so I could start generating some content. I also added shadow maps and tuned the physics so sonic would finally go all the way around a loop-de-loop.
