I liked the art style and the animations. My first play though I was not sure what you are supposed to use the money for, and in my second play though I still had that question. It seemed like there was no cooldown on creating shops and hospitals so if I just kept using them I was too strong. I liked the idea of buying items on the fly with quick decisions, I wish there was some feedback to know that I had successfully bought anything since it was not clear. I assume I was getting stronger since I could kill the enemies in one hit.
If you have time in the future, I would recommend making a web build so that more people play your game. Good job overall!
