A simple game built with TiddlyWiki, introduced in this post.

I decided to see if it was possible to make some sort of game using only the core tiddlywiki with no plugins or javascript. I made a very bare bones zork/interactive fiction type game. It is currently the simplest thing I could make and claim it was a game, but I may add on to it in the future. It uses the 5.1.5 prerelease because the action-setfield widget saved lots of work making macros.
One goal of this is to use nothing besides what is contained in the core tiddlywiki, so there is no javascript and no plugins.
