Way too many ads. If you get a text while playing guess what your gonna get an ad no matter if you respond to the text or not. Any notification from any app triggers an ad even if you just dismiss the notification. It takes too long to unlock "level" mode. Once you do you'll get an ad after every level no matter how quick or slowly you complete the level. The flow of the game is disrupted so much by ads that it takes away the enjoyment of playing the game. Yes you can pay to remove the ads but you should be able to enjoy the game without having to pay. In app purchases should enhance the game not just remove annoyances.

The game is fun. However, there are an UNNECESSARY amount of ads. Every. single. time. you pause the game there is an ad. And sometimes, it reloads an ad so you have to watch another one if you don't unpause quickly enough. Had to uninstall because it burns through data and the ads are way too long (30 seconds each) to have them popping up that often.
