Buggy controls in iOS 13.1 ...please fix – R.TYPE Review

Touchscreen controls buggy...in both non-full screen and full screen where the spaceship jumps unexpectedly to the far right of the screen often during gameplay (first round), unplayable. Problem doesn’t appear in RType II, only RType. Please fix so I can update my rating I love the game. Thanks
