David Sky’s archeopterix-like map of the book (with grades assigned to the various endings).

All possible routes through The Cave of Time.

Each arc is a decision in the story, with the weight/brightness of the arc reflecting the number of unique paths that include that jump. Boxes on the horizontal axis represent the pages of the book in order, with bad endings colored bright red, good endings colored pale yellow, and mediocrity in between. Arcs above the midline move left to right; below it, right to left.
