Use "To File" feature. It's gives you unencrypted json file. Values you want to change are "remainingCum" and "maxCum"
Thank you very much! I'll do it ASAP!
Just a little question. You mean I should edit save file that I saved "To File", right?
(I'm asking because they are ended with ".mdrg")
Man I really can't find any Json files. Can this be course I'm using Android version?
The .mdrg is just the file ending. Inside is text in the json format. That's what I meant by it.
Just open it in a text editor of your choice. If you are on android you might have to change the extension to .txt from .mdrg
