But C isn't as nice to work with. Maybe OP just thought it was fun to see it take shape and wanted to share it. Why do any sort of little side project like this at all? Just seems like everyone is judging this too harshly. If an LLM is reasonably good at this sort of thing, and you think it would be cool to see Quake written in Rust running in the browser, I say just do it and have fun and don't be shy about doing show and tell about it.
