also, just a sidenote which you might already be aware of, a lot of itch.io used to be written in Lua. Check out Moonscript, A language that is like the coffeescript of Lua (https://moonscript.org), and Lapis which is a web framework (https://leafo.net/lapis/) that can use Lua or Moonscript. Itch.io used to be built with both, I don't know if that remains true today.
