The gameplay involves exploring the environment, solving puzzles, and battling enemies. Garfield can also gain special powers by eating certain foods, such as burgers or lasagna, which grant him new abilities. However, Odie is not directly controllable unless a second player joins in, but players can give him orders through whistling or kicking. The game uses comic strip-style panels to convey important story elements, requiring players to make decisions and take actions to progress.
