Game Description: Rainbow Islands is a colorful, side-scrolling action-platformer and a spiritual successor to Bubble Bobble. Players control two characters, Bubby and Bobby, as they travel through various islands, defeating enemies with magical rainbows. Instead of traditional weapons, the characters use rainbows to create platforms, trap enemies, or attack them by shooting rainbow beams. The levels are filled with vibrant visuals, obstacles, and various enemies. The game features multiple stages, power-ups, and the ability to upgrade the rainbow powers, with the goal of defeating evil creatures and rescuing captured inhabitants.
