What happens when you get all 8 pages on slenderman?
He still kills you. Think about it. Why would any monster stop just because you've collected all his papers? :P
*SPOILER* You "win" in which the Slenderman winds up running up right behind you as you turn around and you die like usual. However, this time credits pop up. So really the ending is kinda anti-climactic.
You still die, but unlock new modes, I will not spoil them, because I have never got them all and I don't know what they are :P
it depends. for slender hospice you have to run all the way back tot the entrance and then you win. but sadly ive never beaten the first slender man
