move the .sav file to something more readable

[shirishag75]

Right now, both the characters themselves as well as story/level progression are in .sav format which are not readable ( at least by a text editor).

It would be nice if they could be made into .json or some other readable format by which the user could read which quests have been completed and other things like that.

The game structures are not json-compatible, unfortunately. As far as I know this is due to the use of Python objects as dictionary keys, which isn't legal in json. There is probably a way around this.

An in-game list of achievements, an adventure journal, or something similar should be added.
