Was thinking on learning this run but was curious if the current route has been tested as the absolute best path to take? I remember there being multiple paths that lead to the exits in my casual playthrough, just wondering how thoroughly alternate paths have been tested by everyone (I’m sure it was very time consuming to do). Thanks.

All the timestamps are relative to my current 29m32s PB. I will only comment on the parts I have personally tested. I also don't have, nor remember exact numbers since I've never saved this data. All of the timings I can bring up might not be accurate at all.

2:23 This route was certainly faster (by 3 seconds iirc) than the most commonly used one. I didn't test every possible variation, so it might not actually be the fastest.

4:29 Going into the right arch instead (like ZephyrPlaysPC did in his 30m44s run) was significantly slower in my testing (iirc, by some 2-digit number in seconds).

13:24 From my testing, previous commonly used route (e.g. in IslaMorag's 31m31s run) was timed similarly (down to 0,5s) compared to the route that I've used. I preferred it because it requires less camera movement.
