Derek Gallant from Dreamsake Studios writes in with word that his gravity-manipulation puzzler Ballin is now available for purchase via Desura.

Ballin is a 2D physics-based puzzle game in which players must guide a ball to each level's exit while navigating mazes and avoiding obstacles along the way. The catch: players have no direct control over the ball itself, and puzzles must be solved by shifting each level's gravity. It's a simple but effective gameplay gimmick, and the level design seems quite varied.

Ballin is priced at $2.99. A 15-level demo version is also available.
