The map's architecture

[cantremember]

Rainy Hall and the big door in the Entrance hall

Is this true though? The Entrance Hall door, in my opinion, would be the exit and the Rainy Hall one would be...something. -.-

Isn't the door in the Entrance Hall is opened in one if the endings? Daniel walks towards it as light shine through the opened door, daylight, and not as it would if it led to the Rainy Hall.

Yeah, I've always thought the open gate in Entrance Hall at the end depicted the outside, that and the name of the map also suggested that this hall was the main entrance to the castle.
