About Knock-knock

✦ AI summary

Survive a haunted cabin through the night by hiding from mysterious entities while maintaining your sanity in this psychological horror adventure. Uncover the truth behind the supernatural occurrences by solving puzzles, maintaining the house, and deciphering reality from nightmare-fueled delusion before dawn breaks.

There is an unusual cabin deep in the woods. It had served as a laboratory and a dwelling for three generations of Lodgers.

But as of late the latest Lodger has been noticing weird changes in familiar surroundings; things are missing, noises and rattle heard. Something odd is coming out of the woods. Come night, it seems like someone's made himself at home in the twilight of rooms, attics, and cellars.

You need to stay awake and sane till dawn.

The Lodger is wandering the rooms, evading the unknown, counting minutes till morning. But it's only in the night that he can solve the main puzzle and find the answers. What's going on? Are the Guests real, or are they just figments of his insomniac imagination? What'd happened to the forest? What's happening to the cabin? Is there a line between reality and imagination?

Gameplay details
  • Hide! Play hide-and-seek with denizens of your nightmares.
  • Don't look now! The goal of each night is to reach dawn while still sane.
  • Fill in the gaps. The house aids the Lodger. You only have to fix it up and keep it in order.
  • Seek. The Lodger has lost something very important. The reason for what is happening is somewhere inside. Everything that is happening can be explained, you only need to find the key and bring it to light.
  • Wait. In this game you need to watch and listen carefully. Inspect and scrutinize. You only have to last until the sunrise.
  • Follow the rules of the game! Of course you must first understand the game being played with you.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Knock-knock is a stylistically unique horror game with striking hand-drawn art and atmospheric sound design, but players are divided on whether the repetitive, slow gameplay and heavy reliance on randomness justify the experience. The game's psychological approach—where supernatural events are manifestations of the protagonist's mental distress rather than actual hauntings—resonates with some players seeking unconventional horror, while others find the obtuse mechanics and lack of meaningful progression frustrating.

Feels random. Very frustrating.

What a good idea to have the endgame requirements solely be based in rng. Did the notes you guys find say that the writer wanted the game to be very punishing and rng based?

An interesting horror experience that doesn't rely on screamers or cheap thrills, but intead tries to recreate an eerie atmosphere of a children's creepy story. In this it's successful, I think. But the entire game is just learning what the game wants from you. I got a bad end, and I didn't fully understood that there is another ending, and that there are specific steps (that I completely missed) to get to it. This is the game for patient and immersed, it's sort of a puzzle that obscures most of it's pieces. Seems good, unique, but not for me.

Underrated game, not as confusing as people say. Just takes some trial and error + the Lodger gives you some gameplay tips, sometimes.

The hand-drawn art style is really nice, and the design of the world and protagonist has something genuinely interesting about it.

Очень атмосферно, лес как будто снился раньше, в целом игра стоит своих денег, потому что игр с подобной уникальной подачей и стилем больше нет и не будет скорее всего.

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
