Sorry, I have no idea what a "container Byron" is supposed to be. (And hopefully the interface is not "insane".)
In any case, there will be options to save and load games on the main menu. The save option will appear whenever you have started a game and in a place where you can can save (basically everywhere, though). And there will be a load game option whenever you've saved a game.
To save the game just go the main menu using the arrow on the screen.
