Along with formally announcing the PS3 Slim and PSP Minis today, the company revealed Loco Roco: Midnight Carnival, a new installment in its colorful PSP platformer series.

This third entry to the colorful PSP platformer series introduces a "Boing" move that has players launching themselves across stages and wall jumping. This video also shows off what looks like a new scoring system and a competitive four-player multiplayer mode.

Loco Roco: Midnight Carnival will release as a download-only title on November 1st in Japan alongside the PSP Go's launch. Pocket Gamer reports that the game is slated to release in North American and Europe, but it's unclear if it will release with the PSP Go's October launch for those territories.
