The quickest way is Settings → Report a problem inside the game: it fills in your app version and device model for you.
Open the main menu, go to Stories and tap Restore purchases. Make sure you are signed in with the same Apple Account you used to buy it. Family Sharing members may need to restore once as well.
Progress is saved on your device after every move. It is removed if the app is deleted, and it does not move between devices. If you lost progress without deleting the app, please email us with your device model and roughly where you were.
Settings → Language. The game supports English and Turkish and restarts the current screen when you switch.
Film grain and screen shake can both be turned off in Settings. If a piece of text doesn't fit or overlaps on your device, a screenshot sent to us helps a lot.
