Not a lot of game here, unfortunately. I just more or less constantly clicked on the pet to make the happiness go up and cleaned his poop a few times. Doesn't seem like there's a ton else? I wish the pet did more! Like, anything. Dancing would be cute. Or sleeping? Cooing?
You seemed to have a lot of camera control issues, based on what your tutorial said, but ultimately I think you would have been okay, like, stapling the camera to the center of the room and just letting the user spin the camera a bit. It's also a little too easy to get the camera in a weird state as is.
