I was a beta-tester for this game. This is one of the longest Twine games available. It's about a character who is trapped, and is having flashbacks to how they got there.
It's a sci fi Gane, with much of it aboard a Star Trek-Esqye vessel (although a small one). It deals with the characters relationship with the crew members.
There is an overall framing story as well involving recorded memory. As part of the framing story, the early text is purposely stilted and formal.
