Shadow Plan
A self-contained mobile puzzle where you drag a shed, hedge and tree onto a top-down garden plot. The app computes shadows along the real sun path for the plot's latitude and season, accumulates them into a cumulative sunlight-hours heatmap, and you win each of twelve plots by getting the target bed enough hours to satisfy its planting brief. Fully offline, deterministic, with a shareable result card.
