Just finished packing the new version in an .exe installer.
the game is no longer .zip, it is now neatly packed in an installer.exe, which will install the launcher files and create a shortcut to your desktop
the launcher will check if a new update is available, and if so will download it.

when your game is up to date you can start it from the launcher.

used GODOT 4.2.2 for the game and launcher.
used install forge for the installer.
