I wrote a quick formula to install bunbun via homebrew on macOS: https://github.com/haukesomm/homebrew-repo/blob/main/Formula/devraza/bunbun.rb :-)
Feel free to submit it to the official homebrew tap if you want to!
shell
brew install haukesomm/repo/bunbun
Maybe there's some crazy preprocessing going on that transforms regular code into the donut shape? I can't imagine anyone can grasp any of it otherwise.
