Has a lot of potential if bugs were fixed.
Ipad 15.5 The game runs fine for a while then the touch controls become unresponsive. Possibly triggers after being hit by enemies or opening menus or using shortcut. Switching customized controls from A to B or vice versa restores responsiveness if buttons are placed in a different place. Basically it feels like a floating touch-deadzone is created where you are pressing when the bug occurs.
