Making a Horror Game Scary
GameSetWatch has put up an article about the characteristics that give games in the survival-horror genre the ability to unnerve, startle, and scare players in ways that most games don't. The genre has seen a resurgence lately, with titles like Dead Space, F.E.A.R. 2, and Left 4 Dead posting strong sales numbers. What triggers your fight-or-flight impulses in games like these? From the article:
"Being visual creatures, humans are most comforted by sight because of our ability to discern objects, action and consequences based on a picture. As a result, cutting visual stimuli and sticking purely to audio or speech is one of the best ways to keep a player on their toes. Even with weapons, it's very hard to find what you cannot see, and what you do not know. Even if visual stimuli is used, limiting or obfuscating the player's view can enhance the horror in a game, especially if the player sees it for an incredible short time. This can hint both at the difficulty of an upcoming encounter, or even allude to matters earlier in the narrative that the player will soon have to face."
Low tolerance for failure (taking a lot of damage or even dying when messing up), uncertainity where enemies are (whether a facehugger jumping out of a corner or a ghost that can teleport around you) and generally a feeling of "ohshitohshitohshit" when an enemy engages you. FEAR wasn't scary, you've got a gun and you shoot people with it, neither was Doom 3 (though FEAR was more of a tactical shooter while Doom 3 was just "eat lead, motherfucker!"). The situation must be life or death, not life or slightly less life. You simply can't have a horror game when your main character is a supersoldier with bullettime, massive firepower and lots of health who murders an entire platoon before breakfast.

Don't let the screenshot fool you. It is anything but a Mario clone. If H.P Lovecraft and Stephen King got together, and decided to make a 2d sprite-based platformer, with the intent to CREEP YOU THE FUCK OUT, it would be that. Short game, you could beat it in under an hour if you wanted, though to get the 'good' ending needs a little more work.
Seriously. If you want an example of a game that starts cutsey, but ends on the other side of screaming horror, play that. Preferably, at night, with the lights out. Just don't let a young child play it, or you'll be dealing with a kid having nightmares.
To scare the hell out of me, I absolutely love the Fatal Frame series. Some people say its strong point is having a camera instead of some powerful gun and some people say its strong point is having to look at the ghosts face-to-face and very close to effectively defeat them.
Though I kinda agree with those two theories, I think its "scare power" comes from something else: the fact that the ghosts are "innocent". In FF, like in some Japanese horror movies, the concept is that the spirits are not aware that they are dead, how scary they look and that they can hurt people: they just want to make contact.
For the sake of comparison, consider F.E.A.R.: Alma surely is scary, but there's little doubt she's one fucked up girl trying to kill you. In FF3, however, you have to deal with the ghost of a 5-year-old girl who keeps screaming "daddy, where are you" and whose attack is pulling your arm to call your attention and look at you pleading. That attitude, plus the realisation she's dead, creeps the hell out of me.
