User Reviews

The game is praised for a gripping, well-crafted mystery with strong characters and art, offering high replayability through branching choices. However, progress is often hindered by a ticket-based system and paywalls, plus bugs and unstable performance across devices. Advertising mechanics are a mixed bag—helpful for progression when functioning but sometimes unreliable. Overall, the story and atmosphere shine, but monetization and stability issues dampen the experience.

Pros

Gripping, well-written story with deep, relatable characters and meaningful consequences.
High replayability due to branching paths and multiple outcomes.
Beautiful art and atmosphere that enhance the mystery.
Free-to-play model with ads to earn tickets, enabling progress without paying.
Distinctive interactive storytelling that feels fresh and engaging compared to typical visual novels.

Cons

Ticket system gates progress and can require waiting or purchases, disrupting immersion.
Crashes/bugs across devices can make the game unplayable or frustrating.
No option to buy the full game outright; progress relies on tickets or ads (paywall concern).
Ads sometimes malfunction or fail to load, hindering ticket acquisition and progression.
Occasional slow text reveal or longer loading times can disrupt pacing.

This game is so fun. It’s so life or death. Chose life next day. Chose death you die. Options matter, wrong or correct nothing safe. Other wise it’s a fun mystery game and love playing it. Helps my reading and understanding skills of different characters so yeah love it!
