The control scheme felt rather original. It was satisfying to watch enemies destroy each other, although it would have been nice if there were a little bit more feedback when that happened (I generally couldn't see the enemy bullet; it just looked like the other enemy was exploding for no reason). I was quite pleased when I felt I was able to control the bird.
Given the control scheme and the momentum needed to maneuver, I did not feel that the play space was enough. I was frequently flying out of bounds, even though the character is small onscreen.
The music is upbeat and jaunty, but got a bit grating after a while.
