Did you ever play The Prisoner? Where you go to the psychiatrist and he asks you all these questions, then the BASIC program crashes and prints an error message and beeps, leaving you at the "]" prompt? But it's really an AppleSoft Basic Prompt Simulation to see how you will deal with the program crashing, judging you on if you go "CONT" or "NEW" or "RUN" or "CATALOG"!

>The game occasionally breaks the fourth wall by acknowledging that a game is being played.

It sure does!

Wow, no I didn't, but that sounds like a fantastic game mechanic!
