As of late March, I can run N's godot projects. The steps are
installed godot.app .
unpacked N's .7z folder archive e.g. SG_demo.7z
$ brew install p7zip $ 7z x SG_demo.7z # creates "STG copy"
... and the various project files are available in the godot IDE.
*.tscn - scene file *.gd - godot source file (its own language, similar to python in syntax)
The project has a tree structure of "nodes" each with a .scene and .gd file.
