Neat idea! I've been curious to see how a hypertext-point-and-click interface would work. I wonder how it would feel if it snapped back to "Look at" after each click? I found it tricky to remember to always select "Go to" every time I wanted to move. I think what I really wanted was a default option that was basically go to for doors/routes, and look at for everything else. But I can't think of what command that could be...

(Nice puzzle, too. That level of interaction with the world is fun.)
