I found a couple issues in the "Take me to the door" section: Right as Valve 3 comes into view, you have to go onto the falling platform, but if you walk towards the valve before it falls you'll end up walking in the air. Valve 3 can be collected from up there, but a bar stops your forward progress and you're bound to always being directly above the path. Walk back to where the platform was and you'll warp down to where you should be.
Additionally, a few frames can be saved when you press the button for the door to make it rise. The actor for the door just spawns where it should be, regardless of how far up the door graphic is, so you can hit the button and enter the door before it rises all the way, saving almost 1/3 of a second.
Yeah I experienced the take me to the door bug before and I am still curious if there's a way to utilize it in order to save time.
