My only caveat in this well-written, well executed adventure is it seems a little combat-heavy so if rolling a 1 and someone has to die, it quickly becomes a TPK. Other than that I think you're a genius. The way you combat the one hour playing time (with an option of adding a bit of time) and the excitement about the package is really great. What is it? Is it a baby? And why is that baby going to grow up to become an evil necromancer?
It's a great layout, it reads nicely – well done.
