Condidering most of the CYOA type books are over after about 10 paragraphs, this is pretty good. I ALMOST got through the first time, but made a minor goof. So, not really a challenge, but it's interesting (and ususally funny) to go back and look what would have happend if you made some silly or less than optimal solutions. BTW, look out, some questions ask you if you have or if you found something. I missread the first one, thinking it said something like, 'if you would like to use the key'. Which lead me to believe that the key was in the room there.
