Nice concept, but a few improvements would be great: the overview pic is too small, so it's still guesswork where to go. I got surprised by the birds being enemies, better make this clear. Then I got killed once when I was clearly away from the bird. I really don't know why. A minor detail: the background of the path ways looks like walls. That's a bit counterintuitive. Music is good, but a bit short and therefore very repetitive. Would be fun with some kind of multiplayer mode, I think! (I know that's a hell lot of work, but you know, just dropping the suggestion. ;)
