mrbid/Snowboarder ? reverse-engineered prompt

Build me a simple 3D snowboarding game that feels like an endless arcade score chase.

I want the player to steer left and right to avoid obstacles and keep going as long as possible. The controls should be easy, with arrow keys on desktop and mouse clicks or taps for a web version if that fits. The game should never really end, just keep increasing the score as the player survives longer, and show the score in the window title or somewhere obvious on screen.

Please make it playable and responsive, with a snowy mountain style, a snowboarder character, and a sense of speed. Let me press R to restart with a fresh random run seed during gameplay. If you need to look up current docs online for the best way to build and run it, feel free to do that. Keep it simple, fun, and lightweight, and make sure it works well on desktop first.
