Save Game

Hi.
I made space invaders and want add auto save for game. Every step means starting a save is automatically created.
I also made a menu and I want every time players of the game came out and wanted to re-enter the game click on the game loaded, the game continues to run.
I do not know programming if you please help me.
THANKS A LOT
