Turn a real forest trail in Berlin into an AR game that's actually fun — for kids, outdoors, with no guarantee of connectivity, and a generative puzzle system that had to work differently every run.

Led architecture and full development cycle on a Unity iOS/Android app that blends AR with audio, video, and procedurally generated puzzles tied to physical waypoints along the Müggelberge trail. Built the generative puzzle layer to keep replay value high without manual content updates. Shipped to the App Store and Google Play as an official Berliner Forsten product.
