This original game is based on classical english detective rules. Everyday someone dies and you need to figure out who is the killer. Everybody has a common mystery story of the past. Everybody could have a motive to do this. And you have only seven days to stop the murderer. 

It is not a generic adventure game — there is no happy end in this scenario, you can either win or lose the game (if everybody dies). 

Speak with characters, investigate crime scenes, guess who lies, look at your dreams to find clues and try to arrest the killer before it’s too late. 

— A new murder every day 
— Several original mini-games

— Original gameplay for those who like to think.

*2026-05-01, version 3.2.1*

interesting game

### 3/5 — Неприятно

*2025-12-10*

Самая неудавшаяся часть серии, здесь использование подсказок тебе вообще не поможет. Необходимые предметы на осмотре вообще никак не подсвечиваются, ассоциативный ряд тоже хромает. Может хотели усложнить, но перемудрили

### 5/5 — Great game

*2025-07-29, version 3.2.1*

Great game this is for the people who love to solve puzzles.

### 1/5 — Subscription based revenue models will be the end of gaming

*2024-12-21, version 3.2.1*

The interface and the story is awesome but can’t this developer companies just set a one time price? I just want to enjoy the uninterrupted! But this limited energy model (which newly implemented to so many games like this recently) is killing the pleasure and satisfaction. Just make it a paid game and put a price on it instead of this limited energy blueballs!

### 5/5 — Fortsetzungggg

Bitte bitte bitte Fortsetzung wir brauchen unbedingt Episode 5
