I played the game on the apple. It was brutally tough. My friend bought the "invisi-clues" which had all the answers in invisible ink so you could reveal just "some" of the answers.

I seem to recall that getting the tea and the BabelFish were brutally difficult. The cheese sandwich trap was truly evil. I dont know anyone who beat the game without being told those three things. I may have grown delirious in my old age, but I think those were the only three clues I needed to cheat on.

Too bad you never got off the Heart of Gold, that was the most fun part because you would never die after that - only get sent back to the Heart of Gold to try again. The present from the aunt was both hilarious and useful.

Ah, fond memories...
 

Being too full of pride to get the hints I figured my Guide knowledge was perfect and that the game would pose no challange to me.
And I died,
and died,
and died,
and died,
and died,
etc..
After an embarassingly long time (that I will never reveal the actual length of for the shame of it) I gave up.
 

Did you get the Babel Fish? That was lots of fun.
