Rainbow Islands - Extra Version — About this game

Rainbow Islands: Extra Version revisits Bub and Bob’s island rescue with rearranged stage and boss challenges. The boys attack with magical rainbows and jump through the route toward each island’s larger encounter. Collecting diamonds gives the advance another objective, with their colours linked to where they fall across the screen. Completing the seven-colour set is therefore a positional task as well as a matter of finding another defeated enemy. The Extra layout needs its own route instead of assuming every original-stage encounter appears in the same place.
