Some of the goals are unclear. For example, have 2 groups of trees. I had about eight adjacent forest tiles and did not achieve this goal. Also, it's unclear what you are supposed to do once you run out of tiles. Do you just quit the game? A retry prompt or something would be nice.
I also agree that being able to rotate my tiles so my town looks nicer and makes more sense would be nice simply from an aesthetic point of view! Maybe some little ponds and streams too :)
