Cool, though I wonder if you could get away with compiling Quake to WASM and running it in Apple Watch's browser. Perhaps the FPS there would have been far too poor.
I don't have an Apple Watch but it would be interesting to know what happens when you fire it up on one.
Also debugging would be pain.
And most importantly, performance would be IMHO terrible.
I haven't even though about using WASM, I prefer native code as much as possible. But WASM is actually cool technology in my book :-)
