I know this is a really silly question, but I’ve no idea how to create a save game function for my visual novel (or any game for that matter). To make matters worse, I also have no idea how it would bring all of it back so (Loading a game). If there is a tutorial on here, I’d be more than happy and grateful to read it.
It’s something I’ve taken for granted over the years but never put any thought into 
(I know bad me T__T)
I would think the basic idea would be to read/write from/to a file, however I don’t want to oversimplify something that could be rather complex. At first I thought I’d just save every single variable state the game is currently in when a user saves. ???
Thanks for the help and sorry for the ‘noob’ question.
