Gorgeous game! But as a result of the art, the lack of sound was even more accentuated. I checked 3 different settings on my system to make sure I wasn't missing anything. I was really hoping that maybe the end would have a loud sound to cap the silent story and just make it all wrap together. ;-)
Other feedback is that there were a few jumps that were hard to see due to the foreground trees and the game being stuck to the bird as they jump, also made it hard to judge when to make another jump. But overall this has great potential with that art style!
