Check out the online beta of 3D Stress Ball, which takes advantage of some of the OpenGL additive texturing modes, as well has Havok physics, for creating a realistic environment. http://www.candomultimedia.com/3DStressBall
A level editor is included with the beta, and you can post your custom levels to the forum.
I’m guessing that you were playing Super Monkey Ball when you came up with this game?
It’s enjoyable, but it feels rather slow moving. I think I would like it more if it was faster paced, so quick thinking and reflexes would have a bigger role.
