The game is set in the 4th Dynasty period (3000 to 2600 b.C.). The search is not aimed at the treasures hidden in the pyramid, rather at resisting the curse and discovering the ultimate secret of the Pharaoh, who is inside his sarcophagus.
Only after the secret is disclosed and the curse vanquished, can we go find the exit.
Notes
In addition to the usual verb + object syntax, the programmers adopted a personal way to simulate the "open box with key" syntax: the player can type a verb followed by two objects, separated by an hyphen (verb object-object). Verbs are at the 2nd singular person, and the code doesn't recognize synonyms. Differently from some games of the same period, even "guarda" and "esamina" have different outcomes here.
