I beat every level and need more levels. The last update seemed to be all the same kinds of levels.
I usually run through fast and beat it as best I can, then go back and get 3 stars for each level. Some are a pain to get three, especially when only one bird to throw.
Oh yea, would REALLY like if the game was somehow synced between iPhone and iPad. Kinda sucks that they are not now, so I rarely play the iPhone version much because I have already seen the levels on my iPad.
