I know I’m about a month late to the party here, but I talked to my co-author and got permission to share the room we built for Cragne Manor. This is the bridge in the middle of town which is somehow also in a vast underground cavern. (Zarf, feel free to include it in your site.)
The implementation is mostly mine; the writing is mostly hers. Like many others, we cheated a bit on the “one room” limitation; we built a little state machine to represent the position of the player within the room.
The source is here, since it proved too long to put in a post. Here’s a highlight:

After reading a command when the location is SPO7:
if the player's command includes "[Stelzer adjective match]":
say "[bracket]The word '[matched text]' is a randomly-generated Lovecraftian adjective that could apply to all sorts of things here. Try using another word instead.[close bracket][paragraph break]";
cut the matched text.
