I appreciate the thorough response! I will say I'm a bit like an 80% speedrunner; I love learning the runs to be able to help bolster the community and provide help and resources, but I definitely don't have the time or patience to grind a game to 100%. I was able to get it down to 59:03 for now, there's definitely more room to go, might leave it for someone else to do. We'll see!
I tried practicing the statue upwarp for the training section, but I could never get it to work. I did know about the FPS view, that was my first try for the first collectable in the 3rd dungeon, but blind timing it ended up being fairly consistent. I actually have a lot of trouble getting Snuff's quick kill! And as you suspected it's the door lowering that's the hard part, the upwarp is trivial. And yep, the setups for enemy movement generally aren't too bad, but I assume my setups just aren't precise enough. They are getting better though.
Weird story, but as I was trying to test out key routing, it seems that the green key in Dungeon 2 doesn't persist? No matter how many times I grabbed it and skipped that door, it wouldn't be in my inventory at the conclusion of the dungeon. Dunno why, but that's why I stopped going for it.
I may run it more to keep it fresh and see how far I can take it, but I generally find my attention span for this sort of thing unfortunately doesn't stick. At the very least I'm happy to have pushed it forward a little bit and hopefully future runners will fare better than me. I also included the TAS guide on the speedrun.com page, so hopefully it'll be easier to find these resources in the future. Thanks again =)
