Show HN: Nostalgia Rider

Nostalgia-Rider is a browser toy that mashes up Line Rider [1] and Ski Stunt Simulator [2]. I loved to play both back when they were popular and thought it would be fun to create this.

No accounts or ads. It's a pure static site.

Technical details:

I did pay attention to performance, even if it's overkill. Uses Zig compiled to WASM for the game state. Rendering is done in JS and WebGL reading from SharedArrayBuffer. I didn't think a single language was worth the boundary trampolining and extra tooling.

I tried to get muti-threading to work but that seems to require multiple web workers running instances of the WASM binary. It started to make other things more complicated (probably because I couldn't find the right level of abstraction) so I gave up. Running WASM in a single worker, off the main thread, is good enough for now.
