Thank you! It’s actually a feature of the platform https://texturewriter.com/ which was designed to be …the child of CYOA and a parser.
Since you like literature, try this if you have not. https://texturewriter.com/play/emshort/endure
I found this engine both more liberating and constraining at the same time (compared to a parser or choices). Not sure I’d like to use it again because it necessitates a specific design to work but a curious engine for sure.
