Got this even though the rating was so bad. I love the concept. I thought how bad could it be? I've never been more annoyed by ads than on this game. They happen after every level, and they are LOUD. Also, it's not easy to see how to buy the game to stop the ads (don't even know if it's possible). Besides that, the graphics need a lot of work. If I were the developer I'd give this as a prototype to a great developer (who knows how to integrate ads, and build better graphics and interface) and have them redo it from the ground up. Not ready for prime time.
