I am working on this as well and learning of saving. I would suggest using instance variables andd then pointing those values/strings to a save function, and then load function when requested. I know construct actually saves quite a bit of information with the built in save, but I would still do variables for thins like this. Location and all that may not be required for instance variables, but for loading player stats, for example, thats pretty specific so I understand what you mean to do so non of that gets lost.
I am not sure if the save can be localized or is defaulted to web data or not, but I do believe you are able to specify save and load locations. Looking into this now and will update if I find more that might help!
