Joost van Dongen, a Dutch indie game creator, announced today that Proun is now available for PC as Pay What You Want, so you can choose how much you want to pay for it. 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. A new trailer is now locally mirrored.
