According to qj.net, the game: Sadness, that website is down.
Sucked into the vortex of sadness
That's right, the official Sadness website has disappeared into thin air. In fact, the domain is now available for re-purchase. Well, okay, the splash page is still there, but pretty much, it's gone. And keeping in character, Nibris has yet to officially offer any word about it.
Not that we're expecting any more from them at this point, really. Anything else that comes out about Sadness at this point is just add-on bonus.
