Bubble CoCo 3 - bubble shooter

Bubble CoCo 3 is an awesome game where you must shoot bubbles of the same color into clusters of three or more. Everytime you do so, the bubbles will pop and the bubble stack will get smaller. The goal of the game is to clear all of the bubbles. It's wicked unbelievably difficult to do! I've only seen it done one time. Every time it seems as though you are on the verge of clearing the whole screen of bubbles, I swear, the game knows and makes it impossible to do. This is completely frustrating but also unbelievably addicting.
