I ran this adventure for 5 friends last night, 2 of whom had never played Shadowdark before, and we had an amazing time! The adventure has great atmosphere and evocative imagery, and the scenario presents clear goals and an opportunity for the characters to strategize before initiating the ritual at the end, which they all enjoyed.
The adventure did require a bit of work on my end to expand certain ideas here into something more suitable for my table, for example I changed Aran's cabin into a crumbling, ancient tower so there were more rooms and more opportunities for encounters and treasure. I made sure many of the encounters could still be resolved without combat, like the adventure seems to have intended. I don't mind doing a little work to make an adventure work for my style, especially one with this much flavor.
Overall I highly recommend the adventure, one of the highlights for my players was encountering the children which offered the perfect mix of whimsy and dread (whom I changed into bat-children--giant bat statistics--because one of my players is phobic of spiders).
Great job, looking forward to the next one!
