2023 statement from the creator:

I regret the spelling errors found in the game. I am mildly dyslexic and suck at spelling. Back in 1988, I had no one to edit my writing. I also regret some of the more "cringe-worthy" humor that is inappropriate by today's standards. In some older video reviews as well as interviews, people have used the pronouns "she and her" when describing me. I am transgender and my preferred pronouns are "They, Them, and Their."

Also from the original info file:

About "Caper in the Castro" This game is a Gay and Lesbian based adventure mystery featuring graphics, text, animation and sound. Written with HyperCard® Version 1.2. (Earlier versions will not be compatible) It is the first Gay and Lesbian computer game to be published in the world, as far as we know.

In the game you assume the role of a lesbian private detective, Tracker McDyke, in search of a kidnapped drag queen, Tessy LaFemme. What you stumble onto is an even bigger and more hideous crime with a mystery that surrounds it. (Who is Dullagan Straightman? Who is the mysterious "L.L." that Straightman works for? What is the meaning of the cryptograph?)

The game has a built-in help/tutorial if you get stuck, the best advice is to try everything and anything during your adventure. You never know what might happen! The game is packed with inside humor, puns and lots of perplexing problems.
