This is some next level flabby bird right here! :D it was fun trying to move around like that.
Nice level design, it has some interesting challenges. I like the way it looks, especially the particle effects - very magical :D
At some angles it was a little hard to see, where the boundaries were. Probably because it's 3D. I died a lot at the end of the key-level, because I kept bumping into the ceiling. Or maybe I'm just too noob, heh :)
But I really like the concept, it has a ton of potential. Btw, the star rating is a nice touch too!
