I’ve built a new virtual world. Its multiplayer but you can only choose from 2 characters at the moment. They are actually the couple that run Two Goats in New York. I scanned them in when they visited me in Melbourne.
The clients communicate with my C# server via websockets. Could also use a nodejs server for this. There are a lot of examples of HTML multiplayer games that use nodejs/websocket servers.
If you look at the web console you’ll see the host server address and also the radio stations I’m using.
