It's kinda creative and fun, its quite well made, i have nothing much to say, except that we though the same core mechanics, of a big amount of troops and the click to move, but everything else is thought by you, I was planning on making a game with that core mechanics but instead of town people it was tribe people, hunting, gathering resources, etc, anyway great game, thumbs up!
A small bug fix the camera can go out of bounds, I see that you made the where you click is where the camera goes, one way to fix this is to take the average position of the crowd/people and have its middle and make a 2d raycast can see if can get where you have clicked and if it couldn't reach there, then reach the closest position to where you have clicked and the camera and crowd move to the nearest position, hope that works for you!
