Astraware has released Shape Shifter, a new fast-paced, circus-themed game puzzle game. "ShapeShifter has two fun-filled modes of play; Beat The Clock, where you fill a specified number of rows before time runs out; and Shape Speedster, where you clear a number of rows before the board fills up. As they are cleared, another row appears."
Shape Shifter costs $19.95. More information on the game can be found here. There is also a competition for the game, ending February 10th. More information for the competition can be found here.
