1. Download Godot: https://godotengine.org/download/windows/ (this project uses an addon for GUI that requires C# so you’ll need the C# version of Godot 4.3)

2. Clone the repository

3. Open Godot and import the project by navigating to the directory containing the project.godot file.

Then open the project and away you go.

Godot is an open source game framework: https://godotengine.org/

You would presumably need to download the Godot framework and open it in the framework.

The github repository is a godot project. Godot is a game engine. The quickest way is to download godot. Clone the repository and open the folder as a project in godot.
