Hennessy has some very good twine games, but I didn't feel like this is one. It still has metaphorical meaning, an interesting 'cover story', good narrative voice, etc. like his other games. The story is about a dungeon, and about rpgs and dungeons in general.
However, one of the games features is that every link provides a huge wall of often repetitive text. Also, the narrative voice is jokey/juvenile, whichI personally don't enjoy very much in a game.
Overall, this is an above average twine game, but I don't recommend it. I strongly recommend the other games by the author.
