Write to support@murphysoft.app. We read every message and usually reply within two days. It helps to include your iPhone model and the game version (bottom of the Settings screen in the game).
My purchase did not arrive
Open the Feather shop in the game and tap Restore purchases. If you were offline when you bought, the Feathers arrive the next time the game opens with an internet connection. Still missing? Send us the date of the purchase; Apple's receipt e-mail is enough. Refunds are handled by Apple at reportaproblem.apple.com.
I changed phones or reinstalled the game
Your progress comes back from your iCloud backup when you sign in to the same Apple Account and keep iCloud turned on for the game. The game checks iCloud when it opens.
Game Center did not give me an achievement
Make sure you are signed in to Game Center (iPhone Settings › Game Center). The game reports unlocked achievements again when it opens.
The game is too hard or too easy
Change the difficulty in Settings: Easy, Medium, Hard or Pro. Training is always available from the menu.
Deleting your data
The game keeps no account and sends us nothing. Delete the game, and if you want, its iCloud data (iPhone Settings › your name › iCloud › Manage Account Storage).
