### 5/5 — 짧지만 몰입감 있는 스토리

*2025-10-10*

분위기도 이야기도 마음에 듭니다 다만 아쉬운 점은 패드와 폰 사이 저장이 호환되지 않아 처음부터 하게 됩니다
그래도 언더월드 오피스부터 시작해 다른 배경의 작품들도 해보는 중인데 재미있어요.

### 3/5 — 價格便宜但沒深度

*2025-08-31, version 2.5.5*

雖然只有銅板價，但是感覺浪費時間看了無聊的故事。

### 5/5 — 이런 양질의 게임을 600원에 제공해도 되는지

*2025-08-29, version 2.5.5*

의문이 들정도로 진짜 갓작이니까 당장구매하세요 버프스튜디오는 짱입니다

### 5/5 — 真的…..有點想哭

*2024-07-03, version 2.5.5*

雖然我只玩了一次但真的整都在場雞皮疙瘩
結尾甚至會看哭…….
說實話這是我這輩子花的最值的10元

### 5/5 — 可

*2023-08-04, version 2.5.5*

可

### 5/5 — 다시해도 명작

*2022-04-18, version 2.5.2*

예전에 모든 엔딩 다 봤는데 아르고의 선택 하면서 예전 이약 궁금해서 서포터로 깔았어요. 
훨씬 수월하게 보니 더 좋네요.

### 5/5 — Icloud please

*2021-09-09*

Por favor coloquen una opción para guardar las partidas en icloud… en frustrante tener que resetear el celular y empezar de cero… :(

### 5/5 — สนุกดีค่ะ

*2020-10-17, version 2.4.8*

ชอบเกมแนวนี้มากๆ ขอให้สร้างเกมแนวนี้อีกนะคะ พร้อมอุดหนุนเลย

### 5/5 — 시간가는줄 모르고 플레이 합니다!!

*2020-07-12, version 2.3.1*

스토리도 재미있고 몰입하게되면서 시간가는줄 모르겠습니다 ㅎㅎ
그리고 모든 루트를 다 가보는 재미가 있네여 ㅎ

### 5/5 — 과몰입하면 안되겠네요

*2020-05-24, version 2.3.1*

처음 엔딩 볼 때 너무 과몰입했는지 진지하게 쏴야하나 말아야하나 고민했어요. 주인공의 기억을 쌓아가는 과정이 재미있고 등장인물들 서사도 재미있었습니다
