What I liked: The concept is simple but the execution is what makes it stand out. I really liked the use of the theme and how you even use the loyal citizens to catch the spies.
What could Improve: Right now it feels a bit easy? Granted I did take my time in mapping out where which could be the spies but that is fairly simple especially when you combine the abilities and items you have. Adding more roles like the senior citizens or even lowering the number of items you can have at once would help with this.
Additional Comments: All in all the game provides the good amount of fun. I can easily see you expending on this maybe adding a bit more story to it. Good job!
