Created by the Mozilla team to showcase HTML5. This is a portable MMORPG. You log in via GitHub.io, create a character, and see other players moving in real-time. No server setup required.

  1. Write an HTML5 game (or compile a C#/Rust game to WebAssembly).
  2. Put all assets (images, sounds) in a single folder or embed them as Base64.
  3. Push to a GitHub repo named yourusername.github.io.
  4. Done – your game is now portable forever.
