Oh hey, I got a crowbar, now I can escape :)
*Five seconds later*
"I pull and pull on the lock with the crowbar but nothing happens"
I was NOT expecting that...
If you scare them too much they jump out of the window, however when you complete the game and look at the scene with the guy running outside, there is only a bottom floor window and the window that you're in, which i'm guessing is the sealed room you start in. So I'm asking, what windows do they jump from?
