Puzzle Dimension is now available on Steam, offering a platformer from Doctor Entertainment with more than 100 puzzles where gravity changes add to the challenge. A Mac version is due on August 25 and mobile versions are in development for iPhone, iPad, and Android. Word is: "Brain exercise in 3D - Train your spatial visualization ability by navigating increasingly complex 3D puzzles. The objective "pick all the sunflowers" sounds simple - but Puzzle Dimension is not your ordinary game world. Here up and down are relative terms as the gravity depends on where you roll the ball."
