I have Zen Pinball on multiple devices. However, when I tried to play it on my PS4, there is a delay between the time I press the flipper button (either button on both sides) and the time the flipper on the screen responds. This is incredibly frustrating, and basically renders the game unplayable. I don't know if this is a known bug, but I certainly hope it's fixed soon.
Also, the requirement to enter image verifications on literally *everything* is beyond annoying. What a PITA.
