I used the opportunity to write up a tutorial for it. (Reddit post http://www.reddit.com/r/programming/comments/bm60m/a_tutorial_for_my_text_adventure_language_using/ , tutorial is http://demented.no-ip.org/dw/doku.php?id=xkcd-adventure , example dialog http://tinyurl.com/yh2ndmp ).

D source is http://dsource.org/projects/scrapple/browser/trunk/idc/pad .

Feedback on code and language design is appreciated.
