Love this game yet cannot get "Clue 13" achievement. Any help greatly appreciated...

im trying to find out how it saves

I would like to say that i love these games or ebooks, they make choice significant again, unlike the normal games now-a-days, even games where choice is supposed to matter, but actually doesn't, but then again, with those graphical games, its more harder to maintain those story arcs that arc all over. I have completed it twice so far, but its a nice touch to being able to be an elf or some other fantasy species. Keep up the stories guys and gals....
