Manditory, full-screen, animated adds after almost every word placement. They take three clicks to get through and trick you into getting pushed to the playstore. Makes this game unplayable. It's simply ridiculous that you spend more time in adds than in the app. BAD marketing decision. If you want your adds to be seen and make money, you're not going to make a dime when people uninstall your app because they can't get through a single game without 20-30 of these adds.
