## What is Knock?

An eerie, uncomfortable horror is creeping from PC over to iOS!

"One of the most fascinating and even endearing gaming experiences I’ve had in ages" - GameFront

***
Three generations of Lodgers have occupied the cabin, but lately, the walls seem to undulate, skittering unknowns shift in the darkness, and an unruly growl seeps from the attic. Are they hallucinations pecking at the insomnia-afflicted Lodger, or the gnarled remnants of a darker secret?
 
The woods finally give in to the nightfall, and the dreadful things come out to play.
 
Survive the night while maintaining the dilapidated cabin and preventing the threadbare sanity of the Lodger from unraveling completely. Hide from the grotesque intruders peering from the gloom and seek out the key to ending the Lodger's ordeal.
 
Features:
- A game of survival and troubling madness.
- Hide from the invading creatures.
- Fix the lights and keep the cabin rooms repaired to ward off evil.
- Survive the night with your sanity intact.
- Solve the mystery of the Lodgers nightmare.

### 4/5 — Баги

*2026-06-06, version 1.52*

Почему то некоторые модели монстров у меня помечаются как фиолетовый прямоугольник или круг

### 5/5 — It’s working

*2026-04-17, version 1.52*

Don’t play this game properly, but it’s working well on the latest ios and iPhone

### 4/5 — Игра супер

*2025-10-04, version 1.52*

Игра хорошая, интересная, но на 8 уровне виснет на отдалении экрана и иногда пропадает белая отметка времени и песок на песочных часах

### 4/5 — Игра топ, но багов дофига и больше

*2025-08-21, version 1.52*

Многие противники не отображаются(фиолетовые фигуры). Часы могут не отображать точное время, что не очень хорошо, а так игра стоит своих денег

### 5/5 — Имба

*2025-08-05, version 1.52*

Имба

### 4/5 — 4/5

*2025-07-10, version 1.52*

на 12 айфоне зависает в один момент и приходится заново проходить обновите игру пожалуйста🙏🏻🙏🏻🙏🏻 помогает от этого режим полета на телефоне

### 5/5 — Тук тук тук

*2025-05-09, version 1.52*

Игра необычная

### 5/5 — Топовый топ! Все срочно покупайте и играйте ночью))

*2025-04-06, version 1.52*

Игра топ! Играли с сыном несколько раз, получая плохие концовки. И вот сегодня наконец получилось пройти игру на хороший лад)) Очень счастливы. Разработчикам респект.

### 3/5 — Пойдет

*2025-03-20, version 1.52*

Проходил эту игру на компьютере несколько лет назад, всё в целом отлично, за исключением багов с текстурами. Поверьте, очень сбивает с атмосферы летящее не перекати поле, а просто круглый зеленый круг. Так же плачущий ребенок, его просто нет, вместо него розовый прямоугольник. А так же при отдалении камеры видно затекстурье. Просто после леса зеленые полосы

### 5/5 — виснет

*2025-02-15, version 1.52*

Иногда зависает при прохождении уровней,очень раздражает когда почти дошёл до конца,а она виснет и приходится всё начинать сначала…
