Ran this a year or two ago. Fun on the whole. But one thing was challenging (and I should have given you this feedback at the time, IDK why I didn't). There is a window near the top of the tower. For the life of me, I couldn't figure out if that window is on the very top floor, or the one right beneath it. This turned out to be very important as my players used it to scout the situation in the tower. That could use some clarifying, fwiw.
