Honestly, dude, i feel like your playstyle is simply nit suited to that last room. I don't remember having that much truble with it. What i absolutely despise is the blood corridor, which you didn't struggle with as much as i do. Then again, i AM on Violent so idk
when i play games i heavily rely on muscle memory. But not having any knowledge to ANYTHING before going into the level does not help. I havent played UK in a minute but after learning everything i could do sissy pretty easily. Funnily enough the blood tunnel kicks my ass now lol.
