A puzzler with a simple concept yet absorbing as the levels get more complex. The goal of each level is to maneuver blocks of the same color so that they touch. Use the arrow keys to move the entire set of blocks around the screen. Immovable black squares can be used to prevent certain blocks from moving, allowing you to separate adjacent blocks from each other. The twist here is that when blocks of the same color meet, they fuse into a single block. Although this is the ultimate goal of the game, you'll have to be careful, as you can easily render a level unsolvable through premature fusions.
