Horror, whatever the medium is a surprisingly hard emotion to elicit from an audience. A lot of people confuse it with "shock" or "surprise" thanks to the over-reliance on jumpscares in films and video games, which can be garnered very easily. You could drop a piece of cutlery from a table and shock someone who didn't see it coming with as great effect as a face appearing behind someone for a split second in a mirror.
Fear, (or quasi-fear if you want to get technical) on the other hand is much harder. This requires setup, direction, pacing, and information about the threat of danger this being or object presents being fed to the audience without being explicitly told. It's a suspension of disbelief that's easily broken and there are many examples of horror video games that drop the ball on this without meaning to, and even a few examples of developers intentionally highlighting the silliness of the situation in order to blow off some steam.
