Neverhood Easter Egg - Klaymen First-Room Egg

At the very start of the game, in the first room, you type in "ENTER HAPPYBIRTHDAYKLAYMEN ENTER" (ENTER means the enter button, and ignore the spaces)
You will then be transported to the next room. Then walk back in and you will walk through the door. This only works in the first room, and is definately not a cheat, because everyone can get out of the first room!
