Copy Unity test project to Godot

I have a unity project and looking into converting to Godot. It is a builder kind of game where you place blocks down and load them back. It's a test game at this stage but wondered if as a test it could be converted to Godot to see if that could be used.

The game:
Creates blocks and places them
Can save as json and load
Loads data using json from a website
Uses characters to walk to blocks based on the data
