🎮 Gameplay & Content
• 1. Short-Form NTR Episodes: The game consists of six self-contained scenes focusing on Natalia's corruption by flies. There is no overarching narrative connection to previous works, allowing new players to dive straight into the insect defilement-themed scenes without prior context.
• 2. Skip Function for Extreme Content: Certain scenes include intense depictions such as urine-related humiliation or explicit birth sequences. The game allows players to skip these while still unlocking the scenes in the gallery, ensuring optional exposure to the most extreme content.
• 3. Interactive Exploration: By examining objects on the map, players trigger daily conversations with Natalia. These moments build a sense of normalcy, making the NTR corruption emotionally more impactful as the story advances.
👥 Characters & Dynamics
• 1. Natalia, the Fallen Heroine: A mighty warrior and the protagonist's mother, Natalia genuinely loves her son. Her gradual psychological and physical submission to the flies—choosing them over her own child—forms the core of the game's emotional devastation.
• 2. The Flies, the Lowly Monsters: These weak, mindless creatures act as the corruptors. They symbolize pure lust, with no ambition beyond reproduction, making their dominance over Natalia feel especially degrading.
• 3. Mother-Son Relationship Erosion: The tragedy intensifies as Natalia’s maternal love is overwritten by obsession with the flies. Small daily interactions contrast with her transformation, amplifying the sense of loss and betrayal.
🔞 Distinctive & Explicit Content
• 1. Uncensored Insect Defilement: The commercial version removes mosaics from internal larval views and cross-section scenes during nipple penetration. This includes explicit fertilization by insect sperm, pregnancy, and a detailed umbilical-connected birth.
• 2. No Redemption Narrative: The game firmly offers no salvation or happy ending. Natalia’s堕落 is inevitable, and the player’s role is to observe her full physical and psychological surrender to the flies.
• 3. Optional Intensity with Full Gallery Rewards: Even if skipping the most extreme scenes, all content registers in the gallery. This ensures players can control their exposure without missing unlocks, balancing accessibility with the game’s harsh themes.
