Amazing and considerate. Not many apps are like this one. it does show adds, but it doesnt bombard you with them. it also mutes them for you too, so if youre playing music in the background or just in general you dont have to worry about muting your phone entirely. Amazing! also it doesnt bug you about rating it, all there is a small thumbs up button at the bottom of the menu screen allowing you to enjoy the game and then decide if you want to rate it. game play is nice too. :-)
