Turning paid apps into add supported apps should be banned. The developer could have retired the current version or just stopped updating and created a new ad supported version but instead decided to try and piggyback off this apps popularity. So congratulations. You managed to destroy whatever goodwill you have achieved with one stupid decision. I would have happily paid for more levels or a new app but I wont tolerate viewing ads in an app that Ive paid for. You just lost all future potential revenue from me for anything you put out because I dont trust you now.
