LocoRoco

LocoRoco (ロコロコ?) is a platform video game released worldwide in 2006 for the PlayStation Portable (PSP) handheld game console, and developed and published by Sony Computer Entertainment. The game was developed by Tsutomu Kouno, striving to create a game that was different than other titles being released for the PSP at the time.

Plot
Living peacefully on a faraway planet, the LocoRoco and their friends, the Mui Mui, help grow vegetation and look after nature, making the planet a pleasant place to be, playing and singing the days away. When the Moja Troop comes to the planet to take it over, the LocoRoco do not know how to fight against these invaders from outer space. As such, the player assumes the role of "the planet" that is capable of guiding the LocoRoco around to defeat the Moja Troop and rescue the remaining LocoRoco, returning the planet to its peaceful ways.

Gameplay
LocoRoco is divided into 5 worlds each consisting of 8 levels. In each level, the goal is to reach the end point of the level, with the player scored on the number of LocoRoco found, the time to complete the level, and other factors. There are six varieties of LocoRoco in the game, identified by their color, appearance, and musical voice, but outside of the first "Yellow" one, the rest are unlocked as the player completes the level. The player can then opt which LocoRoco they want to use for a level, however, this selection has no fundamental gameplay effects and only changes the songs used.
