Spacebar to fly. Mouse to turn.
I spruced up the project a bit by making the clouds move instead of the background changing. I also made it so that the wings smoothly make the flying animation. The bird also falls. I used cloning to make the clouds. The clouds slowly move to the right of the screen from the left. Your bird will fly up or down, depending on if your bird is pointing down, or up. I also fixed a weird error where, when your mouse is on the right of the bird, the bird points up. This I fixed by rotating the bird by 90 degrees to the right.
