The player may control one of three characters, Jack (Hii (ヒー) in the Japanese version), Jean (Jin (ジン)), or RB93 (Cacomaru (カコマル, Kakomaru)), in a puzzle game.

Wagamama (ワガママー, Wagamamā) the queen of a country called Lasyland, has cast a spell and trapped Princess Ophelia in a mirror, causing the Kingdom of Bizyland (Fieldland (フィールドランド, Fīrudorando)) to become gray and dismal.

The image will then fade into a "corrupt" version of the landscape, for example, the trees become rotten and buildings become ruined.

When a full shape is completed with no holes in its borders, the smaller of the two sections created is "purified" and returned to the original state shown at the beginning of the level.

If the player allows the character to get hit by the enemies too many times (based on the difficulty), they will be brought to a continue screen.
