Games good, revoked 2 stars for ads

This game is one I paid for to play. Now suddenly it wants me to pay again to remove ads, which I refuse to do. The game deserves 4 stars (I refrain from giving it 5 since its not as good as Sonic 2) but it will not have them until ads are removed. I am not happy to see this. It is an unethical move to have someone pay for an app then have them pay again to remove ads.
