Really cool game ! I love the idea of playing as the pet, and the gigantic, ominous human looking over you is super cute and fun.
The mirror is cool, and I like the idea of changing your mood, but I cant figure out if the Mood actually does anything ? Maybe if it changed your appearance so you can see yourself change in the mirror or something. For a week dev period, it's great. I'd love to imagine some more stuff you could do as the pet, but then again the life of a pet is pretty mundane lol. Nice job :]
