Fall of Eden (FoE) is currently in alpha stage.
To build the game, you need Node.js.
After you have installed nodejs, you are now ready to build and run the game by running the following commands at the root of the project:
$ npm install
$ npm run start
This will start a development webserver at localhost:8080, just open that address in a web browser and you are good to go.
If you want the output in archive form (both as the raw files and zipped), you can instead run:
$ npm run build
This generates a set of files in the dist/ folder.
You can run the game by opening the file foe.html
in your web browser, either from the dist/ folder or by opening http://localhost:8080/foe.html if you are running the dev server.
