Advertisement? For paid version?????

Ok. I paid money for this game right. Before the update this game was awesome. Now I get an advertisement after every level. Really, for paid version not a demo. What were you thinking developers. I bought this game a very long time ago, like iPhone 4 days.
You need to remove adds, then I will change to five stars.
Dont buy until they remove adds, it ruins the experience. Especially when you pay for the game.
