The other day I purchased Noby Noby Boy for the Playstation 3 (a $5 download from the Playstation Network). This is the latest release from the creator of Katamari Damacy, which should be a warning right there.
But, as Illidan may say, you are not prepared for the utter strangeness of this ‘game’.
As it’s impossible to actually describe, I’ll let this video show you. (The game has an option to record videos, so this is of me ‘playing’).
Please, leave explanations in the comments!
