The Blobby Brothers are in a Gravity Maze just to kill some time. In the maze you control the square maze by arrow keys (left and right) or with A and D. The character (Wiz and Waz) are rolling always down, so don't expect anything really hard. Some levels have switches, which opens the same coloured portals. And in some funny levels Wiz and Waz are linked to each other with a gravity beam.
48 levels to beat and those aren't easy. Great game by anevilfree.com productions!
