Sorcerer is the "middle child" of the Enchanter trilogy, and like many middle installments, it tries to go beyond the old game into new territory while developing some aspects.
This game is still focused on scrolls, but it adds potions and many more Zorkian pick-up-and-carry-around items. Many items are items from MIT Zork which have been repurposed.
The writing is, in fact, nightmarish. There is a nightmare early in the game, and don't try sleeping in the first area! You later visit some particularly horrible places, where there are countless ways to die. The game is filled with subtly creepy locations, like (Spoiler - click to show)an underground carnival. And losing is particularly unpleasant.
This game has many red herrings, and one notorious unwinnable state (you must obtain a certain item in the first 25 turns of the game. The game doesn't tell you that).
The game is famous for (Spoiler - click to show)its glass maze, and for its time-travel puzzle. Unfortunately, I had heard about both before, and so I wasn't as impressed by them.
I got up to 205 points before using a walkthrough. I played this game on iOS's Lost Treasures of Infocom.
