Neon City Robot 3D Endless Runner Game

A browser-based 3D endless runner in the style of Subway Surfers. A little robot sprints down a neon-lit city street at night, switching among three lanes, jumping, and sliding while it collects coins and dodges barriers and trains. Speed ramps up the longer you survive, with a start screen, live score and coin display, and a game over screen with a restart button. The prompt is a single English request for one HTML file, with no clarifying questions and App Store-quality polish. Useful for game prototyping or game development demos.
