This game sure is a great horror classic! Very fun, horrifically thrilling gameplay. If you want a challenge, try beating the game on Hardcore difficulty. I did, and got the best achievement you could possibly get as a result.
I've always been a fan of the Slenderman character, even though most don't talk about him anymore, which I get. If you want something scary to WATCH as well, go check out Marble Hornets on YouTube. They have nearly a hundred videos worth of a story, amassing over 9 hours worth of content and story lore dedicated to the creepypasta. It's really good!

The game has an eerie vibe and fairly simple gameplay loop.
Despite the default difficulty being on 'EASY' the whole experience can be terrifying and was a blast to play through, despite the jump scares that occurred.

Short, sweet and simple horror!

This is fun, scary and intruging. 10/10
