The vibe of this game is fantastic! I love the simplistic but consistent look of the visuals... the mood and atmosphere overall is so great!! :D
The flying of the bird looks amazing! My fav is the landing. The way it auto-targets branches, and flaps as it hovers to a land. All feels so great. It was fun to just fly around and explore.
One tweak might be following the bird's 'root' position while on the ground, (instead of body joint). To eliminate some of the camera up/down when moving on the ground. Flying didn't bug me though. The flight anim looks so great... makes me wish he had a little more animation while bouncing around on the ground. (Even if super simple, legs hopping, slight tail/wing motion, etc). But honestly, didn't bring the experience down, just would've made it that much better. Really cool stuff. :) Loved it.
