Well, I mean, you can always get the latest latest version from GitHub, but you have to run it from the source code there, so ¯\_(ツ)_/¯
Source code = the code behind the game
GitHub = a place where a lot of people keep public source code (public source code = "open source")
You can't install or run the game directly from the source code, you'll need to download the Godot Game Engine and do stuff through that. It's kinda complicated and you probably shouldn't go down the rabbit hole.
