I build tools in clojure and games in godot!
Maybe you could dig into a few open-source clients to see how they work with it?
E.g. someone shared a basic lemmy viewer in godot the other day: https://github.com/sevonj/gdlm - it’s rough but probably not too much to read through. Was posted in /c/godot: https://programming.dev/post/48482
Yes! I love using x (and xs) for functions over whatever the thing is (or things are).
