Take the green shapes to the portal of the same color in a 2D world. Without a third dimension, solve the puzzles by pushing blocks and big circles. Besides the ordinary sliding and tossing downstairs, there will be greater and much more difficult levels ahead. In fact, smart minds may even produce some stages of their own for multiplayer challenges. Create 2D worlds of simple controls and hard solutions. Explore the possibilities of the official campaigns and don't lose the geometric shapes when trying to take them to the green zone. All is done with the use of Mouse's left-button.
