At first glance, the latest offering from Taro Ito's GameDesign.jp appears to be just another Tetris clone, but closer inspection reveals gameplay dependent upon color rather than shape. In Porolith Flash, the objective is to stack and group shapes of the same color together to remove them from play.
In this very simple puzzle game designed by Yotan, the [right], [left], and [down] arrow keys are your only controls. Unlike its almost visual twin, Tetris, you cannot flip the block formations to stack them neatly. Instead, the unwieldy stacks that form become integral to the gameplay. This changes up the strategies commonly used in Tetris, and therefore makes for a fresh new variation on the theme.
Blocks begin to appear in a wider variety of colors as the game progresses, and the rate at which they drop also increases, which gives the game an arcade look and feel.
Analysis: As with other GameDesign games, Porolith features the elegant simplicity that we have come to expect from Ito-san. He has taken the design from someone named Yotan, and turned it into a game that fits in nicely with the others on the site. It's not a very deep game, but it offers replay value for anyone looking for a game that is quick and easy to play.
A brand new take on a classic, Porolith offers simple, casual gameplay that will have you coming back to it often.
