Your game is what's between <script defer type="text/coffeescript"> and <script> tags. The rest is scaffolding and markup dictating how it should look. You can edit the file and play now. (Autosave is off.)

And if you want to know how to edit this, what can be added and how to turn on autosaves (and manual saves, for that matter), read the rest of the guide.
