The game is fun, but the ads are beyond excessive. I bought the in-app item to remove ads, and have to recommend against doing that, as it only removes the least intrusive ads. The banner ads at the top and bottom of the screen are gone, but the interstitial video ads remain, along with the way too frequent self-advertising interruptions before and after each level, and every time you hit a "gift" box in a level (misnamed since they just provide you with the opportunity to buy the "gift").
