### 3/5 — First 2 Hrs review

*2025-11-28, version 1.0.2*

I feel like I have no choice. I have to be a psychologist that lean me into 1 choice all the time. If I answered more human… I got feedback like ‘shut up’ ‘do that?!’ ‘I not trust you’… what the heck I try my best to help you out but I don’t know the situation and you can’t say anything cause you’re not trust me? I have the feeling like ‘on your own, best of luck’

### 5/5 — Fun and Intense

*2025-09-18, version 1.0.2*

Love this game. Totally keeps me on my toes.

### 1/5 — Waste of money

*2024-01-14, version 1.0.2*

Game keeps randomly restarting from the beginning

### 2/5 — Great but unbeatable

*2024-01-06, version 1.0.2*

The story is amazing but there is this one part where you need to go to a website but the site is a site where you can publish books and there is no customer support anywhere that I can put a name

### 3/5 — 4桁のコード

*2023-09-05*

他のLifelineシリーズに比べるとテンポが少し悪く感じました。主人公の「待って」から1〜2分の待機が多い…。そしてこれまでの主人公に比べると人間性としてとてもイライラする！…と思ったのですが、これはプレイしてみるとその意図は大体わかると思います。

ただ他の方が書かれているように進行上必要な4桁のコードが現段階の日本語版では手に入らない状態です。そして他の方が書かれているコードとは違うような…？と原語版について調べると、いくつか4桁のコードには種類があるようです。自分が使ったコードを一応書いておきます。

1701

ストーリーの途中で「オタク」という言葉が出てくるのがヒントかと思います。

### 2/5 — Off putting

*2023-01-10, version 1.0.2*

The protagonist Wynn flips between trust and suspicion making it a frustrating read. I found myself trying to keep Wynn safe until she refused to share any info with me which prompted me to push her in to dangerous situations to get anything done. It broke me out of the fantasy because I can be trusted with making life/death decisions for her but when I ask what is in a patient file she refuses to tell me anything but immediately asks for help figuring out where to go next. She constantly reminds you that she doesn’t trust the player. I stopped playing at that point because I no longer cared about the character. David Justus’ work clearly outshines this one when it comes to character building and the bond and trust developed between the player and fictional character. The older games put a better emphasis on cooperation and trust between the protagonist and player.

### 5/5 — What a game!

*2023-01-06, version 1.0.2*

The game seems like a franchise of the original lifeline, but in this case this is a good turn. They turned ‘funny’ game to a real SiFi thriller with several different endings.I wish they made a spin off from this game. Worth to play!

### 3/5 — Mise à jour Apple Watch S7 ?

*2021-10-17, version 1.0.2*

Superbe scénario !
Cependant, j’ai voulu utiliser le jeu sur ma nouvelle Apple Watch 7 et les dialogues ne s’affichent pas correctement, à chaque message, ça bug.
Est-il possible de mettre à jour le jeu ? Je compte bien jouer aux autres également, j’avais déjà fini le premier à l’époque.
Merci pour votre réponse.

### 2/5 — No

*2021-10-06, version 1.0.2*

Not so good as the others in the series. There’s typos in the very beginning. And there’s no incentive for me to keep playing.

### 5/5 — Amazing story

*2021-06-20, version 1.0.2*

Great interaction between Wynn and the player
