Include these details
Your iPhone or iPad model, iOS version, app version, when the issue occurred, and a screenshot or short description if possible.
The Game Center sign-in screen does not appear again
The Game Center sign-in interface is managed by iOS. After it is dismissed, the system may temporarily limit when it can be shown again. Check Settings → Game Center, then use the “Try Again” option in the game.
Is Game Center required?
No. Game Center is not required for the core game. It is used only for supported Apple platform features.
What happens to my save if I delete the game?
In the current version, game progress is stored locally on the device. Cross-device iCloud synchronization is not yet available, so local data may be lost if the app is deleted.
Does the game support Reduce Motion?
Yes. When Reduce Motion is enabled in iOS, screen shake is disabled and intense flashing effects are reduced.
Does the game contain ads or tracking?
The current version does not use advertising or cross-app tracking. See the Privacy Policy for details.
How do I restore a planet I bought?
Premium planets and tips are bought through Apple In-App Purchase and are tied to your Apple Account. On a new device, or after reinstalling the game, tap Settings → Restore Purchases in the game while signed in with the Apple Account you used to buy. The planet unlocks again automatically.
My purchase went through but the planet is still locked
Check your internet connection and try Settings → Restore Purchases. If Ask to Buy is on in Family Sharing, the planet unlocks by itself once the purchase is approved.
How do I request a refund?
Payments are handled by Apple, so refunds are requested at reportaproblem.apple.com. A refunded planet is locked again.
Do premium planets give an advantage?
No. Premium planets and tips are cosmetic only; they do not change weapons, balance or scores. The game is free and complete without them.
What is the Galaxy Pack?
One purchase that unlocks all three premium planets — Lava, Glacier and Cyber — for less than buying them separately. Once you own the pack, all three are available straight away. If you already bought one of them, you do not need the pack; you can buy the remaining ones on their own.
Can my family use a planet I bought?
Yes. Premium planets and the Galaxy Pack support Family Sharing: people in the same family group can use them without buying them again, as long as they download the game with their own Apple Account. Tips are consumable products, so they are not shared.
