Satan. I would advise not downloading it or playing it. not because of the content, which is tame in the version you can get as the original is rightfully gone, but because it will probably make you feel sick and disorientated lol.
I used to think it was a spookypasta and all the after effects were just exagerated, and while i didnt experience the kind of over the top aftereffects as some people say , it did make me feel rather awful afterwards.
Alternatively theres Youtube playthroughs of it still up, but half dont show the full thing.
