Lol, I love ending A, even if S is better in long term obviously. She's too horny to think properly, but once she gets there, she's like: "Wait... House in the middle of nowhere, and I don't even know the man at all... Nope! Not going to become a main figure in this "Boo! Haunted House" circus."
The owner of mansion was obsessed with his wife, he bring her back from the death by put her soul in the doll then invite you to bring your dead body as the new body of his wife, the killer that follow you was his wife who have a body from the previous victim according the note in blood she know the truth behind this mansion but she was killed by mansion owner while fighting him
Another observation would be the ending variations. Not only sweet home (famicom) but also clocktower (snes/psx). I Love ending E for being such a common horror trope.
