One of a virtual avalanche of Tetris-inspired puzzlers, Kirby's Avalanche has players maneuvering pairs of Blobs that fall from the top of the playfield, lining them up in groups of four or more in order to vanquish them from the screen. Boulders, which are destroyed when adjacent to an exploding Blob, clutter the playfield as well, appearing on one side of the split screen when the other player (you, a friend, or the computer) eliminates a large group of Blobs with a single pair. By general standards, Kirby's Avalanche is not at all bad. It has the typically cute Nintendo-style characters and music, plenty of challenge, solid controls, and spot-on gameplay. However, it's not as elegantly streamlined as Tetris or as exciting as Tetris Attack, and is not nearly as addicting. ~ Brett Alan Weiss, All Game Guide
