Warp Passwords

There are secret shortcut passwords to access the different locations of the game. In order to use warp passwords, first, input any invalid password (or empty one) to get the "WRONG PASSWORD!" message. Then input one of the following passwords and press "END". If done right, the message "WRONG PASSWORD!" will be displayed again instead of "SORRY. TRY OLD ONE". Press "END" one more time. The message "THAT'S NOT IT!" with a name of the selected stage will be displayed.

With these passwords you will start from one of the game's locations with a predefined set of money/items and stats corresponding to the selected stage.
