How the book becomes practice
Reading puts ideas in. Retrieval keeps them there. The game is the retrieval.
Walk the world of the book
25 maps, one per part of the book. Signs along the way hold its key ideas, so the walk itself is a refresher.
Battle the characters
121 characters, each a short quiz on one idea. Answer well and the map opens up; a boss guards the end of each one.
Missed ideas come back
Every question you get wrong is re-asked in rematches and boss fights until you get it right. That is the part that makes it stick.
