Haunted Mansion Cheats

Your greatest and strongest enemy you'll face throughout the game will probably be the Floating Maiden. She is dangerous because her strikes are very powerful. Luckily, she doesn't strike often as long as you keep moving. Her gaze is locked on you, which means that if you don't stop moving, she'll have to keep turning to run after you. She's very slow until she's right on you. This'll make it harder for her to kill you. Defeat her quick since you'll face her in the Kitchen first and you'll be attacked by the flying plates. After the Kitchen, she hardly shows up alone. With her counterparts, they can inflict major damage. Not to mention our natural panic response of fight or flight will take over. It's best to keep a balance of both.
The Skeletons are the next dangerous ones. They have shields to protect them and if I remember correctly, they don't run after you; they're long-distance attackers. This is something to take advange of since you can take your time to kill them. Don't shoot at them rapidly when they hold up their shields; you won't do anything. Their blows aren't that powerful, but their defense is major.
My memory is fuzzy of the Grim Reapers, but they almsot outrank the Maidens. They have no defense but tough blows. Fire rapidly.
The only other thing I could give advice on are the Knights. The knights are strong. They have tough blows and good defense since (if I remember correctly) they're made from stone. Be careful and kill them as fast as you can. Hope this was helpful! Good luck!
