I made a very brief CYOA game using Twine called Corvidia.
(on Interactive Fiction Database)
(play it now!)
I had had the copy in a short story (well, obstenibly one) for awhile but the linkages in Twine seemed to suit it better: particularly in bringing to light what isn’t said. And also to have variations in the text that function kind of like the lines of a villanelle-same lines, different context depending on the replay.
Twine itself is incredibly cool and at some point (when I’m feeling less sick) I want to write about it as a gaming tool, and some of the amazing, subversive games made with it.
