### 5/5 — Класс!

*2025-09-27*

Разработчики красавчики!

### 3/5 — Угнетающе

*2024-11-05, version 1.5*

Начало истории действительно интересное, но сама роль, которая была отведена здесь игроку очень угнетает. Ощущение, будто собственными руками убиваешь человека. Думаю, именно этого и добивались разработчики, но лично для меня это слишком тяжело.

### 5/5 — Fckn magnificent

*2024-07-24, version 1.5*

A game that truly challenges one’s moral values and abilities to apply them in practice. Through an immersive storytelling helps you to more understand your own emotions and gives you new ways of thinking.

To make a long story short, much more of an art piece that one would expect form a free to play no ad app App Store game. Totally a must play.

### 2/5 — Has so much potential

*2024-06-25*

Great storyline, I have also played 1 and 2, unfortunately can’t play 3 sense it is in Russian. The story keeps me focused and builds the anticipation for the next step. I couldn’t help but notice that the options of choice have very poor selection, in my opinion the creators have not put in that much effort for your choice based narratives.

### 5/5 — Классная интерактивная история!
