I find it seriously obnoxious of you to claim IN-GAME that the ads are necessary for your game development while utilizing borderline coercion to try and get people to pay $7. You have ads across the bottom of the screen, for upgrades, as well as the every 1-2MINUTE automatic ads. This is overkill and you'll drive more people away than trying to bully players into purchasing your ad free. Shame on your devs.
