In Rainbow Islands: Towering Adventure!, players control the rainbow-magic-wielding Bubby or Bobby as they climb the seven seamless areas of a tower reaching the heavens while defeating enemies with their rainbow powers. Bosses controlled by the scientific genius Dr. Crescent await players at the end of every area. Race through every area within the allotted time to meet the rainbow-colored Holly's Comet. There are three game modes: Story mode, which tells the tale of Holly's Comet; Challenge mode, where players attempt to climb as high as they can; and Time Attack, where players select an area and see how fast they can climb it. Rainbow Islands: Towering Adventure! is an exhilarating action game where you use rainbows to climb into the heavens.
