This game is part of a peculiar brand of IFComp games that are very large, moderately well-implemented, and deeply underclued. Someone said that such game suffer from Erden-itis, from "Travels in the land of Erden', an exemplar of this class of games. Other such games include Town Dragon, The Sueno, Varkana, and a host of others.
You have a big city here, a castle, and a very large endgame. Most of the puzzles involve things that would never occur for you to do on your own.
(Sort of like if you meet a random person in a game. Are you supposed to attack them? Say 'hi'? Ask them about themself? It turns out you are supposed to 'INSULT PERSON'. Why? It makes sense out of the world, but why would it make sense in the world?)
