Ok, but buggy. – Luxor HD Review

On my iPhone 7, with controls set for: -- EXACT shooter position with finger, -- fire when RELEASED, and -- swap sphere with MULTI-TOUCH, sphere swap does not work. It's like the game thinks "swap sphere with SWIPE" option is set, but you can't realistically do that with these control settings. This bug seems to have been introduced with the 64-bit release and has not been fixed with the subsequent update(s).
