Pretty cool concept, even as someone who doesn't play city builders I found it very interesting. I ran into what I think is a problem, tho. After a certain point, no matter what buildings I have or don't have, the grid gets filled up with obstacles until I have no space to put any buildings in it. I don't know if it's on purpose but I haven't found any way to get around this, I just lose. Either way, it's a cool game.
