Well, the link's finally working, and I decided to try it out.
Now I've played and watched quite a lot of horror stuff and it's gotten to the point where nothing phases me. I might think a character's death is grotesque or the "scream chord" might startle me slightly, but they ultimately fail to frighten me, largely because I know that they will never harm me. And even if they could, most horror movie most tend to ultimately kill, so my suffering won't last very long.
Yet this game managed to creep the hell out of me. The first half of it wasn't bad since I figured out that the game was trying to psyhe me out with the eerie calm, but after getting the 4th page I began to spot the Slender Man more frequently. Still, not so bad since he's not very speedy: just gotta figure out the guy's tactics, then use them to my advantage...
And then I saw the empty brick building. I was gonna have to enter the building to find the next page, WITH HIM FOLLOWING ME INSIDE! That was when I realized that the shit had hit the fan.
I can't seem to beat it though: it's like the guy gets way too fast to outpace at some point or another, usually around the 7th page. Best advice I can offer though is to do the brick building and gas tanks first: those seem to be the hardest to escape from. The others are easier since you can "hide" behind trees and other objects while at the same time having lots of free space.
Would you believe I never fully watched the original Indiana Jones trilogy? I gotta correct that someday.
