3D Endless Runner Roguelite Game Builder

Build a 3D endless runner roguelite from one prompt. Swipe across a floating three-lane causeway, jump hurdles, slide under bars, ride carts, grab coins and fire a golden Hyper Dash. Pick upgrade cards, evolve 6 gears into legendary forms, choose route portals and beat 3 bosses that throw boulders, freeze lanes and breathe fire. 3 worlds, real-time shadows, adaptive music. Phone and desktop, installs offline, 2 languages, Steam-ready. No libraries, no assets.
