Most of you probably already know about this anyway, but I thought I would share it with you.

It's a freeware, survival-horror game, based on the Slender-Man Creepypasta story. In the game, you need to collect 8 pages, each related to Slender-Man, without him catching you. With every page you collect, he 'chases' after you quicker. It is set at night, with only a flashlight accompanying you. Obviously, it only has a limited charge. You also cannot pause the game, which in my opinion, is quite harsh. Anyway, links below, and have fun (or not )
