As some sort of "scoring" system, it might be interesting to tell the player how many days/weeks it took them in order to win.
Excellent game. I'd not read the "Overview" (might be good to have it in the game itself) before playing, so I was a bit unsure as to what I was doing or how it all worked, but as I played more and figured it out, it all really came together for a solid experience. Very good stuff. :)
