Is Amnesia only takes place in the castle?

[dogu123]

Hi. I have bought Amnesia nowadays. I want to learn something, is Amnesia only takes place in the corners of the stone walls? If you would like me to give an example for you, the Penumbra: Black Plague was taking place first on the jail, then, different places. Is Amnesia only takes place in the corners of the stone walls, reading prayers for the gas of lantern to not be exhausted, and running from the monsters? Are we doing this always and arent we doing anything another than this? This is my first question, the second question of mine is: what is the length of the game? Is the game is too short? Because I don't like short games too much. Because I bought it and I want to play it as I satisfy.

Thank you for all of your attentions,
