Loco Roco is a platformer for the PSP.
Its specials aren't only the "childish" graphics or the crazy mind-eating music, but also a very funny idea how the control works. The main goal in every stage is to navigate the LocoRoco through the level, eat special berries to grow and avoid enemies called Moja. But instead of controling the LocoRoco to move you have to tilt the world by using the shoulder buttons of the PSP. And that are the main things to tell about this game.
You expect photorealistic graphics? Negative. You expect a complicated and twisted plot? Negative.
You expect one of the most addictive games ever created? Hell yes.
And a very well-intentioned advice: Don't have the music on too loud when anybody is around. They are going to kill you for sure.
