It's just a little custom map with "many" jumpscares. This is for Pewdiepie , and there are many references of Pewdiepie in this custom, so if you are not a fan of Pewdiepie you can't understand and you can't follow the story :).
It was ok, there are some misplaced walls and glitches, and some of the level design is somewhat bad. Also the keys dont tell you what they're to. So i give it a 7/10. Next time more detail :)
