This is a nice game. It is a cool mechanic that bird flight has some weight to it. This makes it feel real good. There was a time when the bird kept turning without me pressing the keys. It kept drifting. I really enjoyed playing through it.
Yeah the drifting was in since the beginning but was never able to resolve it. I think it's a quirk of how I'm blending my animations (because it also blends events which I use to change the player movement).
