I had the joy of playing this adventure today with three friends, two of whom never played a tabletop rpg before. We all had a blast! Bodies were morphed, the floating mirror split the party, goblins and melting men got deeply involved, and the orb was shattered.
I had some trouble finding the right room descriptions as the room numbers jumped around, and an adventure hook would have been helpful, but all in all a very enjoyable experience! My players found themselves really submerged 😜.
