I have tried everything and have ran out of charges to try this on. I can change the coins and gems super easily but the emoji charges are not working the same at all. Same with player level, not working.
The game does have a "playerblob.json" file which is where everything is stored but there is some sort of encoding/encryption on it preventing the human eye from being able to read it (a form of scrambling the data) and I cannot for the life of me figure it out. Ultimately figuring this method out would be the easiest to manage but I haven't seen anyone successfully decode it yet. Maybe there's a smart person out there that can.
