It has nothing to do with Juon but it's an old PS2 horror game with some really freaky/funny shit. You can play as 2 different characters and as I said, they have some pretty freaky moments in it, but some of the "scary moments" end up being really freaking funny. Unless you get stuck on where to go, it's actually pretty short, so perfect for any PewDiePie. =)
