MOTHLIGHT // Vesper-9

Race through a rain-soaked neon city, taking 12 light gates in order across five districts to carry the scattered city consciousness, LUMEN, back to the central Spire.

From walking game to night run

MOTHLIGHT began as a first-person exploration game. You walked five districts, rode grav-lifts and read lore terminals. The third prompt turned it into a driving game, the "Night Run". The city, facades, rain, signs, monorail and holographic moths all stayed, while the walking controller was replaced with arcade car physics, handbrake drifts and boost.

How it works

• City: a seeded 9×9-block city of 694 buildings drawn in a single instanced call
• Windows: interior mapping draws rooms and shops with real depth behind flat facades
• Streets: mirror-wet asphalt, rain, neon signage, a monorail, pedestrians and holographic moths
• Car: the body reflects a live environment map of the city, and the headlights light the street surface
• Stack: about 2,100 lines of JavaScript and GLSL across nine modules, unit-tested city generator and collision, bundled by esbuild into one offline HTML file

Controls & tips

• W / S throttle and brake, A / D steer, Space handbrake, Shift boost (sliding refills it)
• Q pulse the grid, R back to the last gate, C camera, M mute
• Drift through wide corners to refill boost, then spend it on the long avenues between districts

The prompt

Made from the third sentence: "Polish the cyberpunk one too; I want to turn it into a driving game in a cyber city."
