Curated by taste and lineage

She said she was being called to that house. There was never a house there. You go anyway, and it is standing on the spot.

A friend went missing on the way home from school, with no witnesses. But you have an idea where she went, because the day before, not quite herself, she said: I am being called to that house. There was never a house there. You go anyway, half disbelieving, and a Japanese house is standing on the spot. That is the premise, quoted from the store page, and the game is a first-person puzzle horror set inside that one building: you explore it, you find things, you open the parts of it that were closed. Steam's own user tags describe the shape better than its official genre does, listing Hidden Object, Inventory Management, Multiple Endings and Survival Horror alongside First-Person. There are four endings, with a fifth added after release, and it runs sixty to ninety minutes. What makes it worth the trip is the building itself. The store text defines the house with two words that contradict each other, calling it somehow eerie and somehow nostalgic, and the second half of that pair only fires if you have been in a house like it: the corridor, the closet, the room with the altar. It is a horror design drawn on a floor plan that a certain kind of person already has in their body. That is not a coincidence. In an interview with Creators Guild the developer says plainly that the Japanese house in this game is modelled on their own family home. The same interview is worth reading for what else it says. Asked about their team, they answer that they are making it alone so they will skip the team questions. Asked about industry experience, they answer that it is zero, that they came out of a humanities degree and started game development knowing nothing. It took one year and two months against an estimate of about one year, built in Unreal Engine 5. And the reason they started: they were watching let's plays of indie horror games and thought they would like people to play one of theirs. This is that game, and it is the only one they have; a direct check of Steam's developer search under the name Sealio returns exactly one title. Released August 1, 2024 at ¥330, it is at 96 percent across 130 reviews (125 positive, 5 negative), a paid title, not free, fully launched and not in Early Access, with no AI-generated-content disclosure and Steam's content descriptors completely empty. English, Simplified Chinese, Traditional Chinese, Japanese and Korean are all supported, so nothing is stopping you. And yet of those 130 reviews, 85 are in Japanese and 7 are in English. Two honest notes before you go. If the phrase Japanese house horror makes you think of Chilla's Art, that is a fair reflex and this site is not going to pretend otherwise; what is different here is a single continuous building with an inventory and a lock-and-key structure rather than a short scripted walk. And at 130 reviews and sixty to ninety minutes, this is a small thing that is very good, not a large thing.

01First, the one feeling

02Who this is for (and who it is not)

For you

  • You want the Resident Evil shape at ninety minutes and ¥330: one building, an inventory, things found in one room that open another, and endings that branch on what you did inside
  • You want a debut made by a person with no industry background at all, in Unreal Engine 5, over fourteen months, with the haunted house modelled on the house they grew up in
  • You want something with a genuinely strong number that the West has not picked up: 96 percent over 130 reviews, English fully supported, and only seven English reviews to show for it

Not for you

  • You want length or scale; this is sixty to ninety minutes, and the replay value is four endings plus one added later rather than a large world
  • You want something with no visible neighbours; if you already play Chilla's Art, the surface will look familiar, and this pick would rather say that plainly than sell you a false discovery

Resident Evil The critical echo

The origin of this taste: Resident Evil, Capcom's 1996 survival horror, available on Steam as the 2015 biohazard HD REMASTER. Beyond the zombies, its lasting structural invention was to make one building the entire game. The mansion is not a level you pass through on the way to the next one; it is the whole map, and progress means finding an object in one of its rooms that opens a different room you already walked past. The building stops being scenery and becomes the puzzle. Japanese House Exploration is not an official Resident Evil work, and this lineage is a comparison drawn by this site rather than a stated influence. What they share is that shape exactly: one house, items that unlock the parts of it that were closed, and endings that branch on what you did inside. Where they part is the thing this pick is actually about. Resident Evil's mansion is a gothic elsewhere that nobody has ever visited. The house in this game is one you might have been inside as a child, and it does not become frightening until after it has become familiar.
