Finally my 3D space racing game entered the app store after two years of developement. The basic idea was to add the third dimension to an app like the classic arcade games. You control the direction on your glider by device motion and you can play in landscape and portrait mode.
The challenge is to pass clouds of asteroids, space mines, ice blocks, meteors, fire spitting moons and crazy, lethal machines in a competition with four opponent gliders. I used Cocos 3D 2.0.1 and Cocos 2D 3.2 for preserving a maximum of particle system fun!
