It's time to reveal all the cheats for all the Boxx games! -=Spoiler Alert=- xD

Cheats for Boxx 1, 2 and 3:

STAR = Gun Mode
MUG = Co-op Mode (Multiplayer Game)
EXH = Extra Hearts (999 lives)
LVJ = Level Jump: Press 1 to 6 to jump to a level (except Boxx 1 which only has 5 levels).

Cheats for Boxx 4:

COIN = Hard Mode
STAR = Gun Mode
MUG = Co-op Mode (Multiplayer Game)
EXH = Extra Hearts (999 lives)
LVJ = Level Jump: Press 1 to 6 to jump to a level. Press space bar to teleport to a level's boss. You can only jump to the main levels, not the puzzle levels. E.g. you can jump to level 2 but not to level 2-2. But when you press space bar and teleport to the boss you can walk directly to the end door and load the next puzzle level (except in level 3 where you have to kill the boss first).

Notes:

-To activate cheats go to Options > Password.
-You have 1 second to type each letter. If you're too late you will have to type the whole password again.
-Accidentally typing the letters D or Y will also reset typing a password.
-In Boxx 4, if you teleport to a boss and you're in co-op mode, wait about half a minute for player two to join. It has to fly all the way to the boss.
-To reset all cheats go to Options > Default Settings.
