Proun

Proun is a slick and trippy racing game. The player controls a fluffy ball riding down a cable-like rail, trying to dodge obstacles of all sizes, shapes and colors to maintain maximum speed and beat opponent ghosts. Moving sideways as little as necessary is the key to building momentum and reaching high speeds. Going fast fills a bar that creates up to three boost power-ups.

This indie is available as "pay what you want" from the developer's website and features singleplayer championships, leaderboards and splitscreen for up to 4 players. A handful of user-created tracks is also available.
