### 1/5 — Script

*2023-01-02*

I am a fan of the lifeline franchise, this one on particular has very poor dialogue with poor language usage. The words hardly add up and don’t fit in the statements that they are written in. This makes it much more difficult to enjoy the story.

### 5/5 — 超级棒

*2019-06-27*

悬疑设置的刚刚好，结局众多，剧情皮的也是刚刚好，音效四星。喜欢文字游戏的不可错过。
