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 to other titles being released for the PSP at the time. After demonstrating a prototype of the core gameplay to his management, Kouno was able to complete development over a course of one and a half years. In LocoRoco, the player must tilt the environment by using the shoulder buttons on the PSP in order to maneuver the LocoRoco, multi-colored jelly-like characters, through each level, being aided by other odd residents while avoiding hazards and the deadly Moja Troop, to reach an end goal. Along the way, the LocoRoco can grow in size by eating special berries, and then can be split and rejoined to pass the LocoRoco through narrow spaces. The game's bright and colorful visuals and dynamic music soundtrack were hallmarks of the game, earning it several awards from the gaming press in 2006. While the game did not sell high volumes, its success led to the development of four other LocoRoco titles - two sequels for the PSP (PlayStation Portable)/PSP Go, a spin-off for the PlayStation 3 and a mobile version (called LocoRoco Mobile and LocoRoco Hi, depending on the market) for cellular (mobile) telephones.
