It looks nice and rich
At start, I lost. Then I won just building something in a triangle like on screenshot.
Then I replayed it and it was about same experience.
I think it has potential, I just don't like that kind of games
You do not need to keep the triangle style of building. Building in other ways might generate different interesting traffic effects (positive or negative) and you may beat the game faster = better. Though, of course if those kind of games are nothing for you, can't do too much about it :S Still, thanks a lot for playing and the feedback! :)
