From reading the reviews, I knew this wasn't going to be the greatest game but I thought it would be a decent time killer, but I couldn't even enjoy the beginning of the game. After about 5 or 6 levels, every level you complete after that is followed by an ad. Every. Single. One. I was still trying to learn the game, and I can't even enjoy that. And sometimes the skip button is tiny, so you click on the ad instead. So frustrating. Would not recommend.
