Oh boy where do I start with your clueless comment... Slenderman came about A FEW YEARS before the stabbing even happened. Slenderman did NOT come about because of the stabbing, so learn to check your facts rather than toss idiotic statements.
The original maker of the slender game like all horror game developers encouraged fans to make their own versions of his original game. This is a FREE game. This developer isn't making any money from people playing it, so what is the issue? People like you are cancer to the gaming community.
You are the only one who seems to feel the need to whine over nothing, you appear to be very angry at life. If you don't like the game then don't play it and give your criticism. But AT LEAST make your criticism constructive and not idiotic.
