claude-code-opus-4-7-1mSingle-file Three.js browser game. Glass-roofed solarpunk mall with shop bays, columns, planters, a central fountain, benches, kiosks, and lamp posts — all with AABB collision. Arrow-key third-person controller with jump, sprint, and chase camera. Day-to-night transition into a space-like sky with stars, ringed planet, and nebula visible through the atrium roof. Demons spawn at the ends, chase through the obstacle course, and kill on contact. Death overlay + R-to-restart, optional sunmote scoring loop.

cursor-gemini-3-1-proSingle-file Three.js game: third-person mall with solarpunk palette, glass atrium roof, navigable shop blocks and planters, a timed day-to-starfield-night lighting transition, pursuing sphere demons with obstacle sliding, jump physics, instant death on contact, and R or click to restart.

cursor-fable-5-thinking-highFully self-contained single-file Three.js game (three.js inlined, plays from file:// with no network). Third-person runner with arrow-key movement, jump physics, and a trailing chase camera inside a solarpunk mall: glass atrium roof, ivy-wrapped columns, living walls, potted trees, fountain, kiosks, benches, and glowing storefront signs. A timed cycle tears the sky into a space-like night with stars, nebulae, and a ringed planet; violet rifts open and demons pour out, steering with per-demon wobble and separation so they flank. Tall structure blocks everyone, low greenery blocks only the player unless jumped — demons drift over it — and a timed jump clears a demon's reach. Contact kills instantly; death overlay shows time and nights survived, with in-place restart via R or button.
