Frequently Asked Questions
Does the app have ads or in-app purchases?
No. PrimeWall is planned as a paid app with no ads, no in-app purchases, and no subscriptions.
Can I play without connecting to Game Center?
Basic gameplay and local record saving are available. Viewing world rankings and submitting scores require signing in to Game Center.
Why are rankings not displayed?
Please check your network connection, Game Center sign-in status, and Apple's service status. During release preparation, leaderboard IDs and displayed details may change.
Can I reset my score?
The app is designed to let you reset best records and history from settings. BGM, sound effects, volume, haptics, movement arrows, and language settings are kept.
Can I get a refund?
Refunds for purchases through the App Store must follow Apple's procedures. The developer cannot directly change Apple's payment or refund processing.
