Rainbow Islands Evolution - PSP

Set once again in the titular Rainbow Islands, Bub and Bob are now under the shadow of an evil record company who is polluting the ecosystem with a constant, mass-produced musical dirge. With this cacophony causing the flora to wilt and the fauna to mutate into aggressive enemies, only Bub and Bob have the experience to take on the record company and its seven bosses, setting the stage for an entirely new adventure.

The game environment itself has received a major overhaul. The strict vertical ascents of the original have been expanded and extrapolated into three dimensions, with each level's building-block platforms now following perspective and disappearing into the distance. As Bub and Bob negotiate the levels, these platforms will scroll to the forefront as they become accessible. This literally opens up a new dimension for the classic Rainbow Islands gameplay.
