The idea of a virtual flappy bird is great, but this game fails. The camera moves and skews when the phone is stationary, making an awkward and horrible views. There is also an ad during gameplay, which interferes with the trigger. On the side note to the developer, the insertion of ads on a game whose duration of development seems seems to have taken two days is absurd.
