Nice, the score is saved even after restarting the game?
Since there is no additional file in the root folder, how'd you do it?
Did you save it in the user files somewhere?

I use resource script (a class that extends Resource, called also scriptable object). I save "user://save.tres" file, the save.tres is an istance of a script (save_data.gd that extends Resource) with the variable that I want to save. I uploaded the source code, it's not very clear but you can find the save and load functions in the singleton.gd script.
