I love this game!! although I shared it to my sister and she lost her save :C she loved the game but now shes really upset and I wish I could do something to help her. (shes playing on ipad) idk if that has anything to do with it but I'd love any feedback I could get.
If she is playing in the web browser, her save file is stored in browser cookies, so make sure she has cookies enabled for this page. Otherwise, you can backup saves in the “manage save data” button in the options (only in web browser version for now), and can backup and restore save files that way. Unfortunately, there’s no way to recover a lost save file if she did not previously back it up, I’m sorry :<
