Somewhat of a cross between Tetris and Puzzle Bobble, the goal is to clear as many bubbles as possible. Position your character with the left and right arrow keys and drop your pair of bubbles by pressing space. Pressing space again will swap the positions of your falling bubbles. Linking 4 or more bubbles of a single color will cause them to explode, causing everything stacked above them to fall and creating plenty of opportunities for massive combos.
