Hi thank you for your feedback ! Don't hesitate to share some screenshots if you want should be nice to see how you integrated them :D
I will :)
quick note: it seems you forgot an get_tree().set_pause(false) within the first condition of the _leaflet (Hud.gd) function. I had the problem that everything was frozen after closing the menu (I've just used the hud and menu scene so far).
My bad, I will fix that, thank you for reporting it to me !
