Quirky Japanese fun.
The sound is simple as well, using basic cartoony 'blop' noises when your Roco lands on the ground, 'slurp' noises when he (she?) is being attacked by an enemy...etc. The music is the real star however, using a different track for each level of a world, and changing the music depending on which Roco you choose. This has no effect on the gameplay, but the different songs are pretty interesting to listen to, even if they are in an untranslatable language.
Controls need very little attention in this review, you have three buttons, the two triggers tilt the stage and jump, the circle button will split/combine your Roco.
The game also has three mini 'games' and a RocoHouse. The games are designed to obtain new parts for your house, and one is a level editor. All of these must be unlocked. The RocoHouse is exactly what it sounds like. You obtain peices for the house by finding MuiMui or playing one of 2 minigames, you can then place these peices around the house and your Roco will jump around and play in the house. It's actually pretty fun, but collecting all the peices will sometimes be frustrating, as you will often collect the same peice several times, or obtain a different peice that does the same thing as one you already have.
LocoRoco is well worth the price for the uniqueness it brings, and it has quite a bit of replay value if you want to collect all of the peices (there are a lot). It can be repetitive, but its hard to notice when the game is this much fun.
