Regarding some video blips: whenever I enter or exit a room with a grey background, you can see a certain weird thing happens. It's not the capture card's fault becauseI it also affected my tv (even worse, it just goes pitch black for a second then reappears with "video" in the top right corner, as if it completely lost and regained input). I have no idea why that happens, this is the only game I've played with that problem. Really weird.

Time is 6:18 by my watch. Control starts when I exit the first elevator completely and stops when the screen starts fading out at the end.

So, like most Beam Software games, this game is designed terribly. Most of the rooms have nothing of any consequence in them, the only reason to enter them is points. All of the warps I take are 100% mandatory. Most of the "important rooms" aren't even hard to enter, while crappy rooms are surrounded by laser beams and block puzzles. You can easily get stuck if you exit a mandatory room the wrong way.

Tricks used:

1) Hitting select in the top-down parts is a suicide button that starts draining down your oxygen. I hit select as I enter rooms and elevators to "damage" myself so the oxygen countdown is sped up. Floor 21 is the most obvious usage of this.

2) Holding up allows you to turn around without losing run-speed, so I'm able to do a running jump from spaces that normally wouldn't have enough room. I thought this was a tas-only 1-frame turn trick before, then murphagator told me "dude, just hold up". Best usages are floor 6, twice in the warp room of floor 15 (which is the only hard part of the entire run), and twice in the final room. Floor 15 went so well that I actually didn't have to wait for the dino-skeleton-roomba to pass by, which surprised me.

3) Holding left while entering a room where the door has a wall immediately to its left causes the game to fail to reset your x-coordinate, so it will be the same as the last time you exited a room. This is used in the first room of floor 15 (that's why I walk slightly to the left at the start), and twice on floor 24. If you can't tell what's happening the second time I enter the room, I'm spawning on top of the key (because that's where I died), then just holding right until I die. I still don't quite understand this bug, but it saves a LOT of time.

This run is really good, most of the mistakes are invisible to most people, except on floor 22 where I go up slightly more than necessary (oh no!). I only wish I hadn't wussed out at the end and started the "horrible suicide noise" a bit sooner. Look how much health I had left!
