I don't like how the bird dies basically if the cat breathes around it, but this is also a bird that's been mauled by a cat. Still, fall damage? When it's in your mouth? That's a bit much.
I do like the inventiveness of some of the puzzles, and they do actually make sense. I just wish that there was some kind of animation of someone looking at you if you're scoping the place out before bringing birdie with you. That way, I can get a sense of who will actually notice me and how far I should stay from them.
