Location Source
Live GPS + debug GPS. Use `watchPosition` on device, or pin exact lat/lon/heading values for repeatable testing.
A single 9:16 screen handles both parts of the loop: a tilted overworld view for dense neighborhood objects and a Roll View inspection scene when the player is nearby.
Roll Up reuses the Balloon Hunt geolocation stack, but swaps the balloon encounter loop for a city-scale rolling collection game: live GPS, debug coordinates, real OpenStreetMap geometry, dense object spawns, and a growing player mesh.
The reusable foundation is split into four layers: location source, vector map source, world-spawn rules, and encounter mode. Roll Up keeps the same lower layers, then replaces the spawn and reward logic with size-gated object collection.

Real streets, parks, water, and buildings. The prototype pulls local vector geometry and renders it as simple lines and fills.
Dense object clouds attach to real focal points. Amenities, monuments, shops, and landmarks seed themed props, with synthetic fallback anchors when needed.
Map mode flows into a growth view. When the player gets close enough, the same phone screen swaps into a camera-backed roll inspector with attached objects.
