I really like the concept of this game! Once I figured out the the relationship between all the numbers, it became really fun to manage the states. I like the simple art style. The black & white photo adds so much flavor to it. A small bug I find is that the food amount can goes to "-1" if you keep clicking after it reaches 0. But it doesn't influence the overall gameplay.
If you are going to keep develop this further, I wish to see more changing with the scene when I interact with each button. For example, like the light could turn on and off when play is sleeping. Without any changing in the scene, it's kind of hard to tell which state I'm currently at. Like at first I thought I need to click the "bed" button again to get up from the bed after I go to sleep. Also It will be nice if the UI can be reorganized to make it looks easier to track which button is corresponding to which status (Unless you are going for the direction to make things hard to maintain for players at beginning). Also I really wish to see some nice sound design in this game! I almost felt like I heard some haunting melody and camera shutter sounds in my head when I was playing.
Overall I really enjoy this game. Great work!
