You mean at the very end of the game? The game seems like it's only designed to trick you into that very ending :) Are you hoping it will figure out the game based on the context clues? I'm not sure I can find them myself...

A long time ago I did some exercises in "classical planning algorithms", which all feel very like the early part of this game. I.e., how do you get ready to leave if you have to shower, and can't do that with clothes on, etc. A similar planning example involved changing a tire (opening the trunk, removing lug nuts, etc). It was surprisingly difficult to make an algorithm that could figure it out! You could search the state space given the transitions, but it exploded with what was effectively lots of dead ends; obvious to me as a human, but not to the algorithm. Which is to say that this is a harder problem than it might seem.
