I’ve seen it mentioned in comments to threads about other things, but I hope in a future update that we can link our progress to an account (google, etc.). As it is right now there’s the looming anxiety and threat that the app will stop being able to be opened because of a bug or something and being able to uninstall and reinstall the app could’ve been a potential fix. Yet we can’t do so right now because uninstalling the app means losing all progress.
Or we need to change devices for whatever reason then we’d be forced to restart in that instance too. I’m sure many players have chipped in a few dollars or much more than that and wouldn’t want to lose progress due to a bug or something out of their control.
