Proun is an abstract indie racing game in which your craft is attached to a long, looping cable. In order to gain speed you have to rotate around the pole, avoiding the abstract objects hurtling towards you. The new video above gives us a quick look at some of the beautiful environments you can race through. The full version is due out this spring, but there's a beta available now to download and play for free. For more info, check out the Proun development blog . To see the game at full speed, check out an older trailer for the game, embedded below.
