John Bedford (Modojo): If you started gaming at any point onwards from the 80s heyday of home computers, then you've almost certainly experienced the core gameplay of Bubble Blitz before. At the top of the screen, you have colored clusters of bubbles. At the bottom of the screen is a gun that fires new colored balls. Send the next shot off into a cluster of the same color, and they'll evaporate. At the same time, any clusters that had been hanging on will also fall into the abyss, increasing your points tally as well.
