Happy bubble

Control the angle, and shoot! If the bubble come into contact with identically coloured bubbles, forming a group of three or more, those bubbles, and any bubbles hanging only from them, are removed, and points are awarded depending on how many bubbles are removed. As the game proceeds all the bubbles move down the screen after a certain number of bubbles has been fired. You must remove the bubbles from the arena before any pass a line at the bottom of the arena. [Control Keys] Left / Right : Control the angle Space : Shoot
