Funny idea. The pace builds up very slowly, it could be a bit faster, since not much else is happening. I like the bird animation when he gets angry. I think the bar with the exclamation marks is a bit dull. Why not put the bird in the middle of the screen, so the crackers are really in it's face? And make it get really really over the top angry. Angry bird sounds and texts flung at the player (playful insults, but not hurtful of course).
