"Midnight in Salem" is a lot more linear than previous Nancy Drew games, making it easier to speedrun. As you can see, a good portion of this run is clicking through dialogue options and skipping every cutscene.

There are only two randomized challenges, which I good luck on. First is the wavelengths puzzle about 15 minutes in. I did it about 9 seconds faster than normal. Second is the drawers puzzle, about 26 minutes in. I did it about 20 seconds faster than normal, because I lucked out and got a solution that was a near repeat from my last run.

The places where I lost time were the decoder puzzle 17 minutes in and the final room with Mei, 27 minutes in.

Two glitches are used during the run. First, about 20 seconds in, I double-click on the drawer as it's being opened. For some reason, this skips a phone call with Deirdre. Second, I completely skip the computer puzzle about 20 and a half minutes in, by solving the puzzle before starting the speedrun. The game's short term memory stores the fact that the puzzle has already been solved, so there's no need to solve it again. Too bad it's the only puzzle which can be skipped that way!
