Good game but way too many ads
Also, the levels get repetitive. Once you get to level 20 or so you start seeing the same levels over and over again. Although the levels continue to go up rather than resetting to level 1, really you are just playing the same levels over and over again.
Overall there’s only about an hours worth of gameplay and around a half of that is spent watching ads (unless you turn off wifi/mobile data while playing).
