It all depends on how much real imagination you've got. I designed a text adventure many years ago for the BBC Model B. Doors were based on reality. Some opened inwards, some outwards, some had locks (and you had to get the right key). The nasty ones would swing shut behind you and you'd find there was no handle on the inside.
There were, of course a host of appropriate messages :)
What is far more important is that you have a game plan, room list, alternative routes/actions, and most important of all an objective.
