Interesting minimalist take on the city building game genre.
I couldn't quite figure out how the population count works (what does -4/240 mean?). Also, once you are through the first stage of the game and have 10 commercial buildings or something like that, the game is too easy; income grows so fast, you can just keep adding residential, much faster than de required population goes up.
I wonder, is there an effect from how you place buildings next to each other?
On my machine (an older core i7 laptop), the game becomes very slow and becomes unresponsive if you add many buildings.
