story8 positive mentions
  • Strong, noir-inspired atmosphere with a well-written, choice-driven narrative featuring a capable and likable female protagonist.
  • High-quality 3D visuals, polished user interface, and moody, atmospheric soundtrack that enhances the immersive experience.
  • Multiple branching story routes with impactful player decisions, encouraging replayability and planned free episodic updates.
  • Current episode is quite short with limited explicit content and few dialogue options, leading to a feeling of lacking content.
  • Pacing is slow-burn, which may not appeal to players seeking immediate action or gratification.
  • Lacks voice acting and some quality-of-life features like a scene gallery for revisiting unlocked content.
  • story
    28 mentions Positive Neutral Negative

    The story is a choice-driven, mystery noir visual novel featuring a female investigator whose decisions significantly impact branching paths and endings, enriched by mobile phone interactions and cinematic 3D visuals. It explores mature, taboo themes with intense, psychological, and adult content, delivering a slow-burning but engaging narrative full of twists and strong narration. While some find it immersive and well-crafted, others note its current brevity and limited choice variety, though ongoing updates promise further development.

    • “I like that the story can change just by saying yes or no to certain events.”
    • “The story is tight, packed with twists, and the narration is so spot‑on it practically reads like a novel.”
    • “Players will be asked to make decisions such as whether to trust certain characters, which will trigger different story paths (and likely lead to different endings in future updates).”
    • “Story was too short with a major lack of choice options and scenes.”
    • “Rated: 5 for that alone; that and having the nerve to use a mimic of Lexi Diamante from Leap of Faith (a real game with story and everything).”
    • “The story focuses on investigating suspicious disappearances rather than solving clear-cut crimes.”
  • graphics
