It's kind of got MUD energy to it from my understanding, but it's purely browser-based. There's a whole game to it, but the draw for me is the roleplay and the player-built places.
There are rooms but without directions, because they can be arbitrarily connected to each other by doors! Fun fact, rooms USED to connect only directionally because at the time I think they were implemented as linked lists. But now, it's arbitrary and you can do hidden passageways and shortcuts and cool little things like that.
