Madame Leota
Whenever you need a hint or help, press up or down on the directional buttons and Madame Leota will give you a hint which is a riddle you must solve to understand.
Maid's Room
The maid's room in the lower hallway is a maze filled with ghosts and spiders and other creeps. The only way to get through is to find the 4 or 5 doors in the room. When you first start that room, you will be mauled by the haunted spirits that hurt you. That entry room is also the last. When you get through all the doors, you are in the same room you started in. Although, when you start, the light switch is not there by the door. When you get through all the doors the light switch is next to the door. Turn it on and get all the shrivled souls and go to the next room.
Secret Area
In the great hall/first level go to the fire place and go to the left. You will see a bat statue go to it and press "B".Once you have done that go back to the fire place and walk down into it.
Secret of the Graveyard
At the Graveyard, you have to find the Head's brothers. There will be alot of fake heads that are wanna bees. Now,from the begging you'll have a choice to go straight or go left. Go left and press square on the one on the left. Ok,now keep on going that way, and then you'll find 2 more heads. Choose the one on the left. Finally, you'll find three heads on the hill. Stand in front of the heads so that you see a backwards triangle. Choose the head in the upper left. If you do this
correctly, lights will come on, and a huge Castle will come out of the ground.
Ballroom hint
At the Ballroom, you will be pushed by wind. Now, what you have to do is try to get pulled by the spiders web, and when you get pulled to the spider you shoot it,and then another spider might pull you right after that. Keep recently doing this
until you get to the mother spider. Hold in L1,and keep on using the powerful attacks. Eventually, you'll beat the spider and you'll have to face Atticus Thorn. One of the ways you can beat him is, to hide behind a wall, charge up your attack,and keep on shooting him. Remember, after every shot,go behind the wall and charge your attack again.
