Diet Go Go is a 1992 arcade platformer by Data East where players control Indy or Rexy, two chubby heroes on a mission to rescue their girlfriends from an evil doctor. As they defeat enemies and collect healthy food, the characters slim down and become faster. Gameplay is fast-paced and similar to Bubble Bobble, with single-screen levels, power-ups, and cooperative play. Its quirky concept, colorful visuals, and energetic style give it lasting retro appeal.
