This game has put a smile on my face. Super well done for this being your first game, and submitting it to a game-jam as a solo dev! I love the art style, it has a charm to it, and the outro credits/scene are cute.
The game overall is very intuitive, I would suggest perhaps the speed/height of flapping your wings up to be a little higher? But the way that it is also poses a nice challenge.
Great job :)
