Audioverse lets you explore a virtual world with a text + 3d-audio interface.
The monsters growl, the tires squeal, the caves echo.
And it’s multi-player! Not “massively,” more like a group of friends playing through a murder mystery together, perhaps set in a creaky old house in a thunderstorm.
And now it has an editor! The editor even has a game server built in, and lets you edit the world LIVE, while players are in it.
