The characters in the world are a lovely design, and the whole place is very pretty. It has some great music, and it plays in dynamically dependent upon where you're flying in the city. But it's glitchy as all hell, flight not letting you satisfactorily swoop and swish as you might like, with your bird unable to take off from far too many places it can land, and clearly there is such a high expectation that you'll get stuck clipped into the world that it monitors for it and respawns you after a few seconds.
