Hello!
Played for a bit, I like the design of the game very much. I have a few thoughts on a couple things.
1. There should be an "Are you sure?" when you click the delete button on a building. First started the game and thought it was a production icon for the town center and wound up deleting it (Oops :b)
2. Multiple "pops" should be able to work on building a single building to speed up the process.
Just a couple ideas. Looks great though, keep up the good work!
