Epic Adventures started life as Scan Quest — a GPS treasure hunt that pinned ghosts, pumpkins and portals to real lat/lon coordinates and steered players with a compass pointer. Fun, but the pins were the whole game.
The current build — EAS AR Proto on the launcher — is a full set-building tool. You stand in the venue, point the phone, and lay down blocks, creatures and sign boards where the guests will see them. One tap on 🔒 drops every editing control and leaves a pure walk-through — lock it, leave it, run the event.
Everything saves to one hand-editable file, .eascene.json. That file is the whole contract: the tool authors it, whatever runs the scene consumes it. It's documented in the repo, so anything you build on top of it is yours.
