Thanks for your feedback. I wanted to mix fantasy and science fiction. It's a difficult exercise whose result may please some and not others. I understand that.
Regarding the map, I wanted to allow the Warden room for improvisation while maintaining a minimalist trifold design. Creating a mini-map of the town, cave, and observatory seems difficult to achieve while maintaining the artistic vision I had in mind.
Your point about the vampire's powers is interesting! It makes me realize that I need to modify them. I agree with the problems you raise for both Appetite of Terror and Bewitchment.
