Hi,
lately I have been having the issue that the game gets stuck in some kind of zoom mode: Instead of moving the camera or your character touching the screen zooms in or out. The only thing you can still do is interact with icons such as doors or loot or to use the 'Backpack' and 'Run to Exit' buttons. There seems to be no consistent way to get back to normal but to force quit and restart (although sometimes it goes back to normal after a while by itself).
I'm playing on iPad Air.
