Blocker 2.1.1   
by Loren Jamison   

Blocker is a game in which you must clear all of the blocks on the screen to proceed to the next level. This is accomplished by pushing blocks of the same color together to eliminate them. Score is determined by how fast each level is solved.
If you clear the blocks in the wrong order, you run the risk of having blocks that can't be eliminated, forcing you to reset the level, costing you valuable time.
