After falling, when you meet Sarah, you have to play until the last ghost you meet now. Replace the kitchen knife on the table with the meat to get the meat, feed it to the monster, get the handle trigger mechanism, and then change the hammer. Finally, you can open the room nailed with boards. Knock on the board and go out. Go to the ground floor room first. 13 soul and a security code belong to the middle room.
Open the middle room with a password. There are some gold coins and a weapon sword in it. Do not change them. Go back to the stairs and go up to the first floor of the castle.
On the first floor, go to these two places to collect 14, 15 souls and gold coins (you need a hammer in your hand to enter weapons), as well as things that you haven't gone to the globe room before. Now you can explore it. Go back to the first floor and enter the room on the left side of the stairs.
