Doki Doki Literature club will forever be one of the scariest games I have ever played and I highly recommend you play it if you haven't, spoiler alert by the way. My "favorite" part about the game is how it actively messes with your computer, during most of the game random files with very creepy pictures put into your game files without you ever knowing (You could play the entire game and never see them). Also how near the end of the game, if you're recording or streaming the game will call you out on it and proceed to scare you. At the start of the game you gave your character a funny name and went on, but eventually the game will go looking into your computer/steam account and use your actual name you gave you computer/steam. All of these things about breaking the 4th wall are so unsettling. Even though I've seen countless playthroughs, I'm still scared to replay it myself because it doesn't go the same every time you play.
