Instructions: Type ordinary English commands (and then press Enter). Particularly useful commands include "examine <something>", "enter", "exit", "press <whatever> button", "take <something>", "ask <someone> about <something>", "put <something> on <something>", and the movement commands "up", "down", "east", etc. Press <space> when you see [More]. Other useful commands include "wait", "look", "inventory", and "score". Additional commands may be required too. Enjoy!
If you get stumped, consult the full solution file, gpeace.walkthru. (But you should first try to solve it on your own! If you do, let me know, and I will add you to a winners list.) Any comments or suggestions are most welcome.
More information about IF games and TADS interpreters is available on my IF web page. See also e.g. the Interactive Fiction Archive, or Baf's Guide, or the IFDB, or my own IF page. My favourite IF game is Lost New York by Neil deMause.)
