The internal name for the Alaska level on the game disc is "05_GREENLAND". this suggests that the level was originally going to be themed around and take place in the Dutch-owned island of Greenland instead of the U.S. state of Alaska.

Also, internal file names for the Pacific Island level ("07_EASTERISLAND") reveal that it was possibly supposed to be Easter Island (Rapa Nui).
