Well, this is an entry to the Juniper Dev Jam, right?
Generally, when you make a jam entry you want to give the users full access to the game on the web so that they can rate it. After the jam's voting period is over, you can make it just the demo, but for the jam voting period, I'd advise you just build the full game on a WebGL and upload it, then change it after the Jam. Maybe give it a week after the jam to change it too just in case Juniper plays your game, that way she doesn't have to play half a version or a downloaded version.
