I think this is a clever interpretation of the theme. Super smart use of color: I love that the objective icon mirrors the in-world landmarks/progress bars. One of the coolest things about this game is the amount of implied narrative. When I came across a small crowd in a wooded area in the first level my mind immediately began to piece together who these people were.
Honestly, I think with the two colors of crowds, the main objective being to capture landmarks, and the title "Manifesto" you don't really need to additional descriptions to explicitly tell the player what each of these elements represent. This is maybe just a personal preference, but I think there's an opportunity to draw people in by leaving some gaps and allowing the player to wonder.
Very cool, and nice job :)
