The THB manual includes a ton of vital information, including a beautifully written storyline, and tips on how to play. I've provided the German version and the translated English. Note that the manual does not contain any graphics, it's all text (possibly due to budget/time issues).

The full version of the game contained a short README with some last-minute updates to the manual. Nothing too important, but I've included it here for completeness.
