It is indeed quite easy to win. I think building should require a person to work on it (classic empire earth style) and I think trees should give more wood since they do take some work to get. Stone is solved entirely by a single stone mine. I agree that zooming is very slow.

Very easy to win. But I enjoyed breaking your little game within a few minutes. Aside from the obvious need to build upon what you have, my only complaint is the zooming in and out was too slow, and the full screen button didn't work for me.
