The source code of the Soulforged Prelude game (aka SF0).

To get it going:

Create a file .credentials/google-auth-config.json

with content in the format of:

{
    "clientID": "...",
    "clientSecret": "...",
    "callbackURL": "http://localhost:8443/api/login/callback"
}

For this you'll need to create an application in Google developer console: https://console.developers.google.com/

Ensure you're using Node.js version 8.

With that done, you can run the server:

npm install
node index.js --reset

Note: once a save is created you should remove --reset as this parameter generates a new world:

node index.js
