Proun is a strange racing game in a world of geometric objects and large coloured surfaces. You avoid obstacles by rotating around a cable in order to gain as much speed as possible. There is no up or down; there is only the cable to which you are attached.
Proun is made by Joost van Dongen (www.oogst3d.net) and uses the Ogre 3D engine. After six years of development in the weekends and evenings, Proun is finally finished and will be released for PC on June 24th 2011.
