Oh yeah, I wondered if anyone else had seen this! I really love these books. I am putting up Romeo And/Or Juliet as a prize for this year’s competition, since I won’t have an entry ready.
If you like it, you should also check out ‘To Be or Not to Be’, the first in the series. They’re both great, but Romeo And/Or Juliet feels a little more robust as a guided story with a consistent world model --stuff from the play will tend to happen on schedule unless you’ve done something to interfere with it, and a lot of paths tend to converge back into the main story, though it’s still possible to get wildly divergent endings. (There are also multiple mini-stories, including a simulated parser game with a few rooms and a couple of puzzles). To Be or Not to Be is more of a time-cave structure that goes all over the place if you ever diverge from the original story.
