Question about the development of amnesia

[willochill]

This is a question for the frictional games staff that made amnesia:
Which level was the most laborious and time-consuming level in the game to create and design? Why? How long did it take you to fully complete this level, with the map and script? I'm just curious, and working on my own custom story so I was observing some of the maps in the actual game to see how to professionals did stuff, and started wondering about this.
