Kotaku writes: "The original LocoRoco was probably as close as to a killer app the PSP has come; exclusive, unique, reasonably innovative - a great game. Wasn't a perfect game, however, as it had a few problems.
Chief among them was the fact it played like a glorified tech demo, with very little to offer outside of a joyous control mechanism and a catchy theme song. Fast forward to 2008, and we're presented with LocoRoco 2, the game's long-awaited sequel, which has things a little harder than you'd think. Tinker with the perfect control scheme and you'd ruin the whole thing. Add too much to the bare-bones original and you'd ruin the game's charming simplicity."
