Press start. Choose a mode. Use the space bar or click to make the bird go up. Hold down to make the bird dive. I know birds don't live in caves, but who cares? Also rocks in caves aren't the correct color. Also the donut at the end is huge. Also the bird explodes on impact. Also birds don't explode. GODS: None so far
If you beat "literally impossible mode" than comment, and I will put your name under the section, GODS.
