I had the same thought, it probably wouldn't even interfere with their stated goal of running at 144fps (and of course there would be more Go code analysis libraries available in the Go ecosystem). I could imagine plenty of other reasons to go with C++ though - there's still going to be a higher performance ceiling, maybe they plan to support languages other than Go, maybe they want a minimal file size compiling to WASM or to use specific C++ libraries etc. It would be interesting to see the original author's thinking behind it, on the website it's mainly comparing C++ to web technologies.
