Hello, if you want to remove the command window, it would need some modifications to the code. I can show you how, but you need to bring your request to either the forum plugin thread, or my discord channel, cause itch.io isn't very convenient for troubleshooting code.
Also, note that if you go that way, players won't be able to delete save file from in game, and won't be able to load a game from the 'save' menu (when accessing the save scene from main menu while in game). In addition, removing the command window might interfere with some other features of the plugin...
Regards.
