The gameplay is a little bit confusing. I'm not sure what makes the person infected go to a specific direction. The fact that you had to press the nuclear looking button to infect is also confusing. I thought you can just click on the people to infect them automatically. I think a short explanation or tutorial would be good here.
The chain reaction here is pretty satisfying once you get it going. The different types of people are also pretty intuitive.
I like the art style, especially the main menu art. Though I had a hard time figuring out which part of the UI is interactable and which one is just decoration.
The music is a little bit monotone? But I think it fits with the theme of the game. Though maybe the loop is a little bit short.
