Based on the classic arcade series Rainbow Islands, Rainbow Islands Revolution once again takes place in the eponymous Rainbow Islands where Bub and Bob are now under the shadow of an evil record company who are polluting the ecosystem with constant and mass produced musical chanting.
Only Bub and Bob have the experience to take on the record company and its seven bosses, thereby paving the way for an all new adventure.
Each level is an island slowly sinking into the sea, and the player must reach the top of each level, by jumping on platforms and using the most distinctive feature of the game: the ability to produce solid rainbows, which are used both as platforms to stand on and as a weapon.
