Love the idea, its like the bird is learning how to fly all over again. It was a healthy amount of difficulty learning how to maintain control of the flight. There's also something satisfying about having the flap down mapped to the button release. My intuition would say it would be typically the opposite, as in the flap down is triggered when the button is pressed down, but actually I like this control setup better. Great job! This one was very fun and fluid to play!
