Rating Notes:

Our rater collected data in Story Mode on Normal (Chicken) and Hard (Peregrine) difficulty levels. The game required the rater to flap their arms similar to a bird flapping its wings. Our rater noted the activity was constant.

Rater felt that the game requires more energy on Normal difficulty since it would require the player to flap their wings more.
