- Playtime Metrics:
  - Game completion: 12.0h
  - Story completion: N/A
  - Session length: N/A
  - Endgame: N/A
  - Reasoning: The clearest playtime signal is the reviewer saying they spent half a day to finish the game, which supports an approximate gameCompletion value of 12 hours. Another review says a single route takes too long, but gives no measurable duration, so it does not justify a separate storyCompletion or sessionLength number. The mention of finishing all five endings confirms completion but provides no hours, and no review gives a distinct endgame duration.

- Multiple endings provide replay value (weight 0.26): Users highlight that the game includes numerous endings, including shocking bad endings and around eight to nine dialogue choices, plus five endings and an FD with extra routes. This variety encourages repeated playthroughs.
- Engaging character contrasts (weight 0.25): The tsundere sister's harsh exterior versus inner dependence and the protagonist's otaku facade versus inner darkness create strong character dynamics. These contrasts make the story engaging.
- Sincere pricing and classic status (weight 0.25): Reviewers note the pricing is sincere and consider it a classic work, even one of the twelve divine works. Its visual impact at the time was compared to a Mars-Earth collision.
- Appealing audiovisual presentation (weight 0.25): The music, voice acting, and art are appealing, with a clean art style and standout sister design. The HD remaster further enhances the visual experience.
- Focused and sweet daily life (weight 0.25): Daily life scenes are light and sweet, and the small scale avoids padding, keeping content focused. The diary-style pacing allows finishing a route in one or two nights.
- Well-developed heroine Himeki (weight 0.24): Himeki is praised as a full and well-developed character design and a really good character. Her personality is likable and adds to the story's appeal.
- Twisted brother-sister relationship (weight 0.18): The story features a taboo brother-sister relationship with twisted contrasts, which some find stimulating and intense. It is noted for its bold thematic exploration.
- Famous work by Nanaka Mai (weight 0.17): The story is a famous work by author Nanaka Mai, and the review is positive toward both the game and the author. This recognition adds to its classic status.
- Convenient interface features (weight 0.14): The game includes added jump function and F/F11 for quick fullscreen, improving usability. These small features enhance the overall experience.
- Attractive character art (weight 0.11): The art style drew reviewers in, and the character art is attractive, contributing to the game's appeal. It is a classic work with appealing visuals.
- Includes happy ending (weight 0.09): One happy ending exists, providing a satisfying conclusion for players. This adds to the emotional range of the multiple endings.

Common complaints:
- Patch Required But Not Included (weight 0.69): The Steam release ships without the content patch, forcing players to seek it externally. The patch is only available via Denpasoft or Baidu Cloud rather than the official storefront or publisher channels.
- Severe UI and Interaction Lag (weight 0.61): Interaction input, button responses, quick save/load, history viewing, and scene transitions all suffer from severe lag and stuttering. The old game system performs poorly overall.
- Disturbing and Malicious Story Content (weight 0.59): The narrative contains bloody, extreme NTR plots and shocking twists that leave players uncomfortable in every ending. Many scenes cannot be skipped and the moral framing is questionable.
- Achievements Blocked Without Patch (weight 0.51): Multiple achievements including the Biological Alarm achievement cannot be unlocked in the current version, and four extra mini-theater achievements require the incomplete patch. Players report achievement bugs making some permanently unobtainable.
- Ending Balance and NTR Controversy (weight 0.5): Only one of five endings is happy, all five contain NTR content, and the patch adds NTR while skipping it removes story content. The hidden choice chain to the better ending is counterintuitive and easy to fail.
- Poor Translation and Localization (weight 0.43): The translation has major problems including mistranslations, missing words, inconsistent terminology, and untranslated puns left as-is. Character names also display incorrectly in some scenes.
- Frequent Crashes and Freezes (weight 0.4): Pressing the quick save hotkey crashes the game, and skipping story text causes the game to become unresponsive. Some keyboard shortcuts and debug keys also trigger crashes.
- Unclear Patch Distribution Communication (weight 0.34): Publisher announcements on Steam, the official website, and Bilibili say nothing about the patch, and player-shared links are deleted by moderators. No Google Drive mirror was provided for Japanese fans, and faster downloads require payment or a VPN.
- Clichéd and Poor Story Quality (weight 0.33): The plot is very clichéd for a game over a decade old, later developments are infuriating, and the story quality is poor overall. The adaptation is poorly done.
- Missing Visual and Audio Polish (weight 0.3): Scene replay lacks CG preview, transition animations are missing in some scenes, and a background image is absent in one scene. The MV and thank-you list cannot be skipped.
- Protagonist and Sister Unlikable (weight 0.3): The male protagonist is extremely scummy and his later actions are awful, while the sister is stubborn and uncommunicative. The game treats the sister character callously.

Recommendations:
