Sorry Tony ;(
It was a decent run, would've been quite a bit better if Sub Headlight and especially the Key had been at better spots, but I'm still happy with how things turned out.
I was also surprised to find out that the Brute did in fact not go for the Helicopter, which would normally have killed the run, but he got stuck in the door I had jammed, which can sometimes happen (a 1/3 or maybe 1/4 chance of him going to that specific door, and then just pure luck that he actually got stuck there instead of just breaking it down)
Also if you're confused as to how the monster didn't kill me; when you activate the sub, the monster enters a weird state where it doesn't react to anything you do and cannot kill you. It leaves this state as soon as the doors to the Sub Room is forced open, which thankfully didn't happen here
