Here is your review

This game was fun at first when I purchased it. It came with one campaign and promised additional levels in the future. After you release one additional campaign you release two more and charge for them?! Thats very misleading from the start if you plan on adding levels for money make the app cost a higher set price and all updates are free. I am so tired of the way you app companies try to steal peoples money. When I go to the store and pay $60 for a game on Xbox I dont go home and have to pay more money for more game content, its all inclusive for a set price. Work your margins better and stop being leaches on society.
