This gave me a chuckle, especially as a high school teacher. The game consists of two parts: a 1000-line text manual and a 35-question multiple choice test.
The game encourages you to do exactly what most students do when studying: start the assignment first and only look up answers as you go along.
The text is dry, an imitation of standard technical writing, but sprinkled with a variety of frightening or hilarious spooky situations, like scissor lifts made of solid flesh or horrifying accidents brought on by improper rituals.
Overall, there's a lot of effort here and the extra flavor is good. But a simulation or parody of a boring thing is often, itself, boring, and while there's a huge effort here to alleviate that, it doesn't fully succeed. As an idea, though, the whole setup is very clever.
