This was one of my first text adventures, so I knew, coming into this, that I would have a hard time. But I was pleased to see that there weren't many moments that I found "unfair." The descriptions had a nice way of subtly making sure the player is aware of the important pieces of scenery in the rooms so that the player can figure out for themselves where they need to go to get an item. The game author was also very nice and helpful.
My favorite puzzle was the wooden door -- this is the kind of puzzle that you can solve for yourself without needing anything other than your own creativity.
