"If you visit the suitably unconventional site with the cute URL - o--o.jp - and click on 'BOY's daydream #1', you'll see a series of images that shows four BOYs playing together while BOY says, "Even though it may be offline... I want to play multi-BOY!"
When we interviewed creator Keita Takahashi last month, he suggested that the game would get a "big update" around two months after release.
There's also a suggestion that some new music will be added, in 'BOY's daydream #2'. Noby Noby Boy currently only has one background theme, a gently plucked acoustic guitar.
"Guiter music are good," says BOY in the second strip, ungrammatically, "but music from castanets, triangles, and maracas is something I'd like to listen.""

This is awesome! Local multiplayer is exactly what Noby Noby Boy needs to bring people back into the game, I've always wanted to play this game in local multiplayer
