## AI Review Analysis

Analyzed Sep 1, 2026

### Strengths

- It combines the Death Note IP and unique roles with an Among Us-like genre to provide a distinctive social deduction experience.
- Unique rules, such as L restraining players instead of eliminating them immediately after a vote, expand the scope for mind games and strategic decision-making.
- It offers strong immersion and enjoyment not only to Death Note fans but also to players who enjoy mystery and social deduction games.

### Weaknesses

- The extreme lack of active players and public lobbies makes matchmaking difficult, and it is often practically impossible to find a game.
- There is considerable frustration that the developers have abandoned the game and provide few updates or official communications.
- Suspected cheating, hacking issues, and rude or discriminatory community behavior have been reported in some lobbies.
