Based on the classic arcade series Rainbow Islands, Rainbow Islands Revolution is once again set in the so-called Rainbow Islands where Bub and Bob are now in the shadow of an evil record label polluting the ecosystem with a constant, mass-produced musical chant.
Only Bub and Bob have the experience to take on the record label and its seven bosses, setting the stage for a whole new adventure.
Each level is an island slowly sinking into the sea, and the player must reach the top of each level, jumping on platforms and using the game's most distinctive feature: the ability to produce arcs- solid rainbows, which are used both as platforms to stand on and as a weapon.
