Rainbow Islands Evolution

Rainbow Islands Evolution is a game in the Bubble Bobble series for the PSP system. It is also known as New Rainbow Island: Hurdy Gurdy Daibōken!! (レインボーアイランド ハーディガーディ大冒険!!) in Japan. It is an enhanced remake of the arcade game Rainbow Islands.

Bub and Bob, the two main characters in the series, are against an evil recording company that seeks to pollute the Rainbow Islands' atmosphere by creating constant musical noise, therefore wilting the flora and mutating the fauna. Bub and Bob use a hurdy-gurdy as a weapon to create the rainbows.

The game follows the same vertical-scrolling system from the original, but it expands to a third dimension as there are platforms in the background which become accessible through the course of the game.

Reception
The game received "generally unfavorable reviews" according to the review aggregation website Metacritic. In Japan, Famitsu gave it a score of 16 out of 40.
