The Ocean House was the "Gone Home/Firewatch/walking sim" of its time. There's no gameplay.
The Ocean House suffers from the fact that you never really feel vulnerable, which makes it feel more like just an homage to certain horror movies rather than something that's scary in itself. Quite early on you realize that it's just a scripted ride of scares, and at that point all sense of horror flies straight out of the window.
What? There's
nothing to imply that there's no danger. The only way you can know that is if you played it before or looked it up. Ocean House is
great horror because of the uncertainty. Up to that point in the game, anything dangerous you saw, you could W+ M1 and kill it. That all goes out the window when the house itself starts attacking you; there's nothing to fight back against. The scene in the kitchen is sheer genius, because unlike the earlier sections in the hallway, you can't run, you can't take cover, there's nothing whatsoever to interact with, but
you don't know that. There's no apparent end to the attacks so you keep trying to find a way out until they finally stop on their own. Don't tell me you were bored during that section and you just stood there and waited for it to be over. The apparent "rules" change a few times during this section, and you're never allowed to find your balance and feel safe. Yes,
having played it we all know that it's just scripted sequences, and you probably can't die there even if you try; but you have no way of knowing that when you're stumbling through for the first time.
