The game has become more unstable. It frequently freezes, usually as I improve my score and therefore it does not save the higher score.
And now Rovio has removed the option of deleting the least desirable award when you spin the daily bonus wheel. I guess they want to make sure you have to buy the awards you most want. Greed prevails.
Also many of us do not have Facebook, nor do we want it. We should be able to connect to Game Center or be recognized by Rovio to ensure we do not lose our levels should the app become non-functional.
