I got the email. I had exams, and usually I respond to emails within 24 hours, but I couldn't because of the exams.
It would be nice to start out with the Tower of Wisdom. I think it's animation and behavior is pretty-well spelled out in the images at the top of the page, so you should be easy in that regard. Also, the artistic theme of Dark Magic (bloody spikes) is pretty consistant throughout Dark Magic, so once the Tower of Wisdom is completed, there should be no confusion over any beautifications of future buildings. What do you think?
