So I loaded it in Twine. First of all, the passages are arranged to form a NSFW image in the Twine editor. Secondly, it is indeed splitting into two different games. Here’s the starting passage:
Passage: "Splitter"
{
(forget-visits: -1)
(forget-undos:-1)
(replace:?sidebar)[]
(if: (saved-games: ) contains "good path")[(go-to: "good start")]
(elseif: (saved-games: ) contains "bad path")[(go-to: "bad start")]
(else:)[(set: $path to (random: 0, 1000))
(if: $path > 388)[(go-to: "good start")]
(else:)[(go-to: "bad start")]]
}
