I noticed that VR Planet Defense is completely broken on iOS 16. (Well, not completely, you can still view ads or check the leaderboards 😅)
The game was built by a really old version of Unity, and the last update was Jun 17, 2018. Fixing won't be easy. So I made a decision today to remove it from App Store. I'll keep the Play Store version a bit longer though since it still works.
I had a lot of fun building a VR game for Google Cardboard. Maybe I could get back to it some day.
