Random scope creepy ideas
- in general, new monster (or a quirk about peach develops) per section of castle?
-The water in the basement, something DEFINILTY has to be done with that. Like maybe it floods suddenly. or alerts some unwanted attention.
- the eel comes for you if you go in water. Perhaps a star powerup lets you swim fast enough to evade it and reach another section?
-you know the haunted piano with teeth? would be funny if something else in the castle did that out of nowhere.
- dark mario comes from mirror room, maybe acting as your reflection at first, but then the AI takes over and it gets a mind of its own and slowly starts walking towards you?
-dry dry bones spawn somewhere in castle field protecting a statuette. Not a main threat, but they slowly walk towards you as a group outside until you get indoors and its kinda unnerving. Maybe unexpectedly, mario encounters them again behind a door and they resume their chase.
- some of the paintings have hands come out and reach for you if you get too close? A spooky scare at first, then mechanically turns into a "you have to risk running to get past this safely " area
