This is the original classic puzzle game for the Game Boy. You play as Mario in a lab coat, clearing viruses by matching colored pills. It's absolutely worth playing, a perfect portable version of a timeless formula.
The gameplay is pure, fast-paced puzzle action. It requires quick thinking more than twitch reflexes. The unique mechanic is that you rotate and place two-colored pills, giving you precise control to set up chain reactions. Grab your Game Boy and give it a shot.
