It's dizzying at first, but gets easier once you get used to it

Since it's 3D, it's difficult to play until you get used to it. Honestly, it can make you feel sick. But once you get the hang of it, you can spin the camera around 360 degrees to see wherever you want while tapping, making it easy to play. It's the kind of game you want to play mindlessly when you have too much free time. You don't really feel like it's fun or boring; you can play it with your mind completely blank.
