If you haven’t realized, I like interactive fiction (IF) and have written several posts on creating IF. Someone at Google likes is to because Google has created an entire lesson plan on creating IF in Google Slides.
Although it is broken up into 4 lessons, It is going to take more than four lessons to get through the material. Especially when you get to the linking of Slides part, which may be a pretty foreign concept to the students.
The lessons have several videos to go along and reinforce the material.
