updating game engine

Ive started to transfer the project from Godot 3.5.2 to version 4.0. Almost all files are no longer behaving as expected. It will take me some time to do this transfer properly. 

Also i realised that i exported current version of the game to not save your local high score in a correct place.  which is ironic because i added all high score lists to the game but forgot to change a boolean.
