I made a cat owner simulator game. First of all, I was inspired by my own life experience. Although the subject was physics, the first system that came to mind was about my cat. So after asking Jason's consent, I made my original idea of a cat owner simulator. After all, raising a cat also belongs to the category of "physics", isn't it? 

In my game, the cat system is made up of two main subsystems, a cat feeding system and a cat pooping system. The two systems are linked to each other in sequence. In my System Journals, I wrote out the elements and interconnections of both systems. I will repeat them briefly here. The first is the cat feeding system, where we need to earn money to buy cat food, then feed the cat food to the cat, and the cat eats the cat food and becomes full. When a cat is full, it will not eat cat food anymore. The cat poop system came after is similar. When the cat is full, it poops in the litter box. When it empties itself, the cat gets hungry again, so it goes back to the previous system to find cat food. In the cat system as a whole, it's a balancing system -- the ultimate goal is to keep the cat's mood at a level that's not going too low, not adding up endlessly. The two subsystems that make up the cat system are also balanced systems, producing negative feedback to the stock in order to maintain balance between the various elements.

After I figured out the elements of the two systems and how they relate to each other, I made a simple prototype in Machinenations. And then I moved them all over to Unity. I made several different sprites representing different elements of these systems. At the same time, I used C Sharp code to express the interconnections between them numerically and logically. I think the most interesting part of my game is that the player is overwhelmed by the elements of the system and the relationships between them, and how hard it is to be a cat owner. Of course, this is much harder than in reality, as cats eat cat food and poop dozens of times faster than in real life. 

If I had more time, I would have made the parts of the game more realistic, rather than just button clicking. But so far, I think I have a rudimentary cat owner simulator. Anyway, play some systems and have fun!
