The title graphics, UI and transition animations are great. Not sure what I can say about the actual gameplay itself -- it's a real pity you get knocked DOWN by the bird, rather than have the option of bouncing off some for distance bonus à la Toss the Turtle. That gashes points for gameplay, but you've got added points for UI.
What really annoys me is that there has to be an ad EVERY TIME you finish one round, rather than have it done and dusted at the beginning. Look, we know you're looking to earn with this game. But you ain't gonna get far if 1) it's the same ad every time, 2) the gameplay has to be interrupted by it all the time. We gamers get frustrated... and I am certainly frustrated at this. How are we even going to go through the process of unlocking more items if we have to be interrupted each time?
