The problem with a player slender is that nothing is stopping him from backstabbing everyone when the game starts.
And since he runs faster too, getting all the papers is impossible.
I won't kill anyone until they get the first page, and even then I will only injure people. I will be the only person controlling the Slenderman until I figure out a way for others to do it. The real Slender game is VERY difficult. It's hard to get to even 6 pages.
What we need is a real slender where looking at him kills you, and he cant walk into the players view.
That's why I had that onPlayerGaze topic in Suggestions and Requests. I wanted to make it hurt or kill people when they look at me.
An actual Slender add-on would be sweet. A bot that can appear and disappear and kill players when they get too close to him. And it would get harder as you get more pages (more deaths, Slender comes closer and appears more often).
