Cool little game. However, I am unable to get gold or even silver on some of the levels. I'm sure it's possible, but it sure seems like there's no way to do it since I'm not even close on some of the levels. Does going back to earlier levels later in the game help you in any way (do the buildings start off more advanced or anything if you revisit levels later)? Anyone have any pointers?
