ALLOW
In the original Jet Set Willy, certain rooms had guardians marked in the game's data but never activated. The word "ALLOW" was associated with permission flags for these dormant guardians.
The game also shipped with The Attic Bug. Software Projects distributed a cassette fix. Matthew Smith called the development "seven shades of hell."
