itsvijaysingh/Snow-Rider3D — reverse-engineered prompt

Build me a simple browser version of Snow Rider 3D that feels like an unblocked arcade game people can open and play right away. I want the player riding a sled down snowy slopes, dodging trees, rocks, and other obstacles, collecting gift boxes, and trying to survive as long as possible while the score keeps going up. Make it look snowy and fun with a clean start screen, easy controls, a game over screen, and a quick restart so it is addictive and easy to replay.

Please make it work well on desktop and mobile browsers, and keep it easy to host as a static site. If there are already game assets or build files in the repo, use those instead of reinventing everything. It would also be great if it feels smooth and lightweight, includes basic sound if available, and supports installable offline play if that is already set up. Look up current browser docs online if you need to.
