Hello :) for every rpg game there isn't auto save; before opening the app, drag with the cersor the file "Save01" and leave it onto the app (pocket mirror). When the game opens instead of "Gaze" click "Recollect" and choose the save file
When you make a save into the game this save becomes a file named Save01. If you make four saves for example the files will be: Save01, Save02 etc and these files appear right below of the Quick_Save file (where it says Pocket Mirror. exe, right below there are the files: Pocket Mirror.ini, Pocket Mirror.rgss3a, Quick_Save. Right after Quick_Save the files Save01 etc take place) If you haven't saved the game there will be no file.
