Password (0000) displayed before playing a level in HTFA 2.

As a throwback to older games uses password save system, the HTFA games also use this feature, though the passwords are more or less used for instant access to any level once the player knows of such password.

This feature is introduced in HTFA 2 and is applied until HTFA 5. HTFA GB is the only later HTFA game to not use any kind of saving feature, not even passwords.

  • While the first level of HTF Origins (Happy Green Land) has a placeholder password like other first levels in every other HTFA games with password feature, typing said placeholder password will instead take the player to Stage 0 (the one where the player can meet Neena and Tacho before leaving and there are no hazards and enemies at all) since they share the same password.
