Press the pause key, type in the name "RACHEL", hold down the 'Shift' key and tap the 'G' key to freeze the time limit (another source says type: "HELL", the hold down the 'Shift' key, and type "GRACV). For infinite lives, type: "FAYE", 'Right Shift','C','Ctrl','Return'. For infinite energy, pause the game and type the name "CAROLILY" (another source says type: "ILYCAROL"). Unfortunately the game may crash at the end of level three.
