Cool stuff 
PS: for web experiments I’d currently recommend the stable Zig version 0.15.2, there’s some hickup in the wasm32-emscripten target currently which breaks the sokol-zig web builds: Wasm32-emscripten builds fail linking because of pthread dependency - #3 by floooh
I have a gut feeling that the Zig nightly is currently entering one of its unstable moon phases again
