Nice game. Checked it on iOS, will also test it on Android. The first thing, I found on Android, was the wrong targetSDK. Please check it, because you have to do it anyway: Important TargetSDK and NDK changes in Android app publishing
Edit: It would be nice, if it could use the API 28 (Android Pie) API for the cutout. So it will behave be like the iPhone X(S). Currently it will ignore the larger statusbar and the screen will be letterboxed.
