A guide that contains most skips/tricks that have been found in this game.

3rd Ghost Skip: Skips having to trigger the ghost cutscene before heading to the hotel basement. Both sides of the wall can skip the cutscene trigger.

Skipping Ghost Text Boxes: Shaggy's sprint (R button) can be used to skip over Ghost Text Boxes. I as well currently believe Shaggy's hitbox is bigger then Scooby's and therefore lets you avoid some text boxes easier.

Electricity Ghost Out of Bounds: Using the ghosts electricity orbs you can damage boost yourself out of bounds. This trick is situational as not every chapter contains these enemies and you will get stuck out of bounds if you aren't getting continuously shot. This trick works with every character each having slightly different setups.
