Programmer credits:
Execute the "Use Shield" command while the image of the axe is displayed. "SHL", the initials of programmer Steven H. Landrum, will appear.

Harmless traps:
Intentionally die near a castle during the first attempt at game play. Press Reset and run into one of the castle traps before the copyright information disappears from the screen. Your character may now leave the trap without any penalty, although "Trap" will still appear. Note: There is a limit to how many times this trick may be done.
