I really like the Oriole sprites and how they bob with the gravity when tapping the arrow key as well as having to navigated around to get to the worms.
I think I would have preferred some more wasps or other obstacles, like forcing the bird to jump over the pipes instead of being able to walk past them. It felt pretty easy to maneuver around and avoid damage.
Pressing start in the middle of a game will reset it, I am not sure if that is intended.
