I like the setting, sounds and theme. However the gameplay and controls took me some time getting used to. Maybe remove the forward movement when pressing space and make it work like a flappy bird mechanic or just make the crow fly in-place. Then press left or right to start accelerating towards that desired direction. When released, the crow decelerates. Also maybe add life-steal to the attack, the red claw effect really made me think of life-steal. So I think your game has an interesting concept and I can see the fun, but needs a bit more polish to gameplay.
