RohanChacko/Subway-Surfers ? reverse-engineered prompt

Build me a playable Subway Surfers style game in the browser using WebGL 2.0.

I want it to open from a simple game.html page and be ready to play right away. The player should run forward on a track, dodge obstacles, collect coins, and be able to move left and right with A and D or the arrow keys, and jump with the space bar. Please include a police chaser, barriers, trains, finish line, and a few power ups like a jump boost and a fly boost. Add background music, textured objects, and basic lighting so it feels like a real game and not just plain shapes.

Keep the layout and styling clean, and make sure it runs smoothly in the browser. If you need current WebGL or browser specific details, look them up online.
