- You can log onto Alan's computer and start the ghost hunt at the beginning of the game, if you've played through the game before and know the password is "purgamentum".
- You can open the locked box in Nancy's room at the start of the game, if you've played through the game before and know the solution.
- You have to go up the singing stairs twice: once during the ghost hunt, and once to get the key that unlocks the puzzle outside Jane's room. So while speedrunning the game, you want to do both at the same time.
- You don't have to solve LouLou's magic word puzzle to learn about the second hidden passageway; you just have to see LouLou's magic word puzzle.
I didn't get very far on the speedrunning strategy, and my notes are full of questions like "Is it necessary to check the locked door?" and "Do you have to tell Linda about the woman in black?"
I stopped planning a speedrun, because I quickly ran up against Jane, the Speedrun Killer. She makes you do all those time-consuming, randomized puzzles like Bul, the jigsaw puzzle, Go Fish and Petroglyph Punch. I can't think of a way to skip those puzzles or make them go faster.
If you guys want, however, I can try working on a speedrun for a different Nancy Drew game, or at least plotting out a general strategy.
