Theres an ad after every single level. This infuriarates me beyond what I thought. I thought it couldnt get any worse but boy oh boy, it got worse. After getting to about lvl 130, you cant complete the game without the cheats. Its almost completely impossible. After hitting 3 ads in the span of 5 minutes, I gave up playing and have uninstalled it. The ads are unbearable at this rate.
