Is Amnesia only takes place in the castle?

[Damascus Rose]

He needs 42 minutes.
And he already know the game. So, everyone could do that.
But it's not the goal of the game.
I needed 8 hours, but looked sometimes into a solution because I atucked in the cells and the control room.
If you play proper, you'll need about 10 hours.

Amnesia is made to play slow.

Everyone could do that? I'd like to see you finding all these glitches and pulling them off in a speedrun!
