Make a 3D kart racing game in one web page: a neon night circuit floating above a futuristic city, with loops, jumps, boost pads and seven rival karts. WASD or arrow keys to drive, Shift to drift (a long drift earns a mini-turbo), Space to use the item you picked up from item boxes. Give the karts suspension, drift sparks, speed lines and a chase camera that leans into turns. Add a HUD with lap count, position, a minimap and the held item, a 3-2-1 countdown, and finish and results screens. Make it look as polished as a console game. It should feel fast the moment it loads.
