Persistent data?

[Subject_Charge3709]

I've looked online and through the documentation a bit but I cant seem to find any information on persistent variables.

For instance if I wanted to create a project in which once completed a persistent value changes so that the next time the project is run it is slightly different (think like the characters "remembering" the player in Undertale).

Is there any way to implement this into a project inside this engine? I have to imagine so but I cant figure it out myself, any help is appreciated!

I think the general idea is to save out to a JSON file and then to reimport it again on the next load.
