Another game that I used to find scary when I was younger, and now it's not that big of a deal. I still found it better than the "Eight Pages" one, since you could pick different maps.

The ultimate Slender experience and the influence for so many horror games until FNaF, it singlehandedly lit the slender flame and it also burnt itself out of mainstream relevance do to oversaturation of content. It's really repetitive but cool.
