Sadly there is not much challenge to the game at all, and most of the times it feels like a casual relaxation application. Enemies come into view; I tap or swipe them, and avoid incoming slow moving enemy projectiles. There is no indication when I get hit, no flashing or anything beyond just having the health bars at the top removed."
