I need help with save system

I really bad at creating save mechanic. I need to create mechanic that

1. Save settings in menu (language, volume, controll)

2. Game save(when you pressing new game, that saving every second and or when game close. Like in The Binding Of Issac)

3. Deleting save, if player die(also like in TBOI)

4. Loadind menu on start of layout after catsen(And when going from game to menu)

I really need your help, cuz that is the last thing before demo release

System 'save' will save the game. That's all you need, and system 'load'. The deleting save you refer to is to restart the game, so create events that get you back to where you started then 'save' again. The settings should be global variables which are saved whenever you perform the save action, you could save whenever the settings menu is closed for example.
