opus 5.5 simply follows a haunting directive i wrote into the game. it drives the sentient AI that builds new rooms, characters, entities, and experiences forever. coolest part is even as the creator of this game, i don't know what to expect in there. 

multiplayer with proximity chat is supported from day one so go play it with your friends.
