I thought this was a really good example of a small scale city builder. It had easy placement, a sense of building up as the game continued and had a couple different buildings to cerement that sense of progression. The visuals are good, though I think it could be improved by having something other then blank space around the zone, maybe some prebuild buildings so it feels like your building within a city or something. That's really the only criticism I could think of, because everything else is on point.
