I really enjoyed this game! I'm a big fan of city builder games so I got a lot of enjoyment out of this game. I loved the sprites and the limited color palette -- well done!
Super fascinating concept of swapping between the robber, the policeman, and the mayor. Being an architect and having to consider how to expand the town in the way that benefited the robber and the policeman was a really fascinating mindset to get myself into! I agree with some others in the comments that it's too easy to camp the jail and arrest the criminal over and over as the policeman. I'd be interested in seeing this turn into a full game, the concept's really cool. Great work!
