raqote VS macroquad

There's several different approaches you could take, but I'd probably suggest macroquad as the easiest. I've also used minifb for windowing + a drawing library like raqote or tiny-skia.

You may specify font family by adding a line font = "Source Sans Pro" into a config file (path is $HOME/.config/yofi/yofi.config). Though, perhaps you meant "Source Code Pro" which is unfortunately broken in third-party rendering library. You may specify font size similarly with font_size = 12 line, though the binary from the last release doesn't support it yet, so you either may built yofi from master (as simple as cargo b --release), or wait for the next release (I think it will be on this week).

See the macroquad docs for full details on building a WASM game.

Any opinion on ggez? I don't like how everything in macroquad is global state https://github.com/not-fl3/macroquad/issues/333

I prefer examples like the ones in Macroquad: https://github.com/not-fl3/macroquad/tree/master/examples. I'm not against advanced examples, but the priority should be extremely clear, minimal, self contained ones.

There were even discussions about deprecating static mut. Even if you think you got it right, there are too many things that might go wrong, like aliasing. For example, macroquad needs a complete rewrite because of their static mut.

It's based on macroquad and you can play the wasm version here: https://unvirtual.github.io/yinsh-rs/

The reality is that I have used unsafe that is also unsound out of convenience because fixing it is a papercut too many. And this tends to be common! I know enough to spot unsoundness in other projects (sometimes even early). But not enough to be confident in my own abilities to write sound unsafe code. Why? Because it's really flipping hard, that's why!

Given that you are making a game, you might want to consider using a game framework such as https://github.com/not-fl3/macroquad/.Macroquad has full support for WASM, and will allow you to render your game both locally and in the browser via WASM depending on how you compile it.
