Frozen Bubble is a cute little game. It is written in perl and uses SDL. Unfortunately, it is still X11 only. But never fear, Windows users, the Frozen Bubble guys have you covered. Along with the source code, they provide images that you can boot, just so you can play Frozen Bubble. How considerate.

The game itself is rather simple. One has to knock away the bubbles on the screen (match your colors) before they get below the line and freeze you. Not only do they get closer to the line when you screw up and pile more on, but the ceiling closes in if you take too long. As simple as this sounds, it's a very addicting game.

The developers of Frozen Bubble are so kind that they even go so far as to accommodate the colorblind, and provide the -cb flag so that bubbles will have special markers on them. How considerate.

If for no other reason, you should check out this game because its developers are such marvelous people.
