This examples tests gamebook formatting, not so much game mechanics or references. Currently there is nothing here really. This section contains some tricky characters to quote, like \} and \{ and " and ' and \textbackslash. HTML will probably not like <div> or \&boom;. You can make named references like this (\textbf{\autoref{section5}})
(just happens to be exactly the same syntax as in emacs org-mode btw). There should be an image below as well. If something broke, turn to \textbf{\autoref{section2}}, otherwise turn to \textbf{\autoref{section3}}. \begin{center}
This is where you should end up when you follow the named reference from the starting section. From here you can go to the second named section (\textbf{\autoref{section4}})
