All programming and art assets are entirely handcrafted. Our goal in integrating AI was to enhance NPC intelligence—making their behavior and responses feel more lifelike—and to create a new kind of immersive experience that blends narrative and deduction, rather than using AI as a tool to develop the game itself.)</h2><h2 class="bb_tag" >&lt;Storyline&gt;</h2>    On the mist-shrouded outskirts of 19th-century London lies the mysterious Baskerville Manor. The corpse of Sir Charles Baskerville is discovered in a nearby marsh—eyes wide open, hand clutching his chest, his face frozen in terror. There are no visible wounds, but the ground bears the tracks of a monstrous hound.    “It must be—the Baskerville curse! That demonic hound has returned!”    “Am I doomed to this fate too? No… I don’t want to die—Ahhhhh!”    Shadows loom within the manor, while danger festers beyond its walls. A suffocating fear grips everyone like the hand of a demon on their throats. Soon after Holmes arrives at Baskerville Manor at the request of his friend Maud, a series of new murders erupt—mutilated bodies in the marsh, the corpse of a woman in a neighboring estate’s fountain… Are these seemingly unrelated crimes connected? What hidden truth lies behind the Baskerville curse? As the investigation unfolds, the truth begins to surface, until—    “Sherlock, you once said that every brick of Baskerville Manor whispers… Yet some secrets drown even beneath the roar of the Thames.”    “Then we’ll need sharper ears—like a certain doctor who insists on carving Christmas pudding with a scalpel.”<h2 class="bb_tag" >【Game Features】</h2>====== Free Chat! Immersive Detective Simulation ======<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3939410/extras/1bbf8172e9c8dced3f7294ddf80e198b.avif?t=1783486336" width=1560 height=878 />No dialogue choices, no rigid scripts—you can freely chat with NPCs: negotiate, interrogate, coax, compliment, threaten, or tempt… anything you can think of! NPCs are no longer just lines of code—they are “alive,” infused with AI-driven personalities. Witness their reactions in real time: a suspect feigning calm under interrogation, hastily covering up lies when caught, gossiping about neighbors’ secrets, or shifting blame onto others… AI brings every character to life. You’ll never know if they’ll help you solve the case—or stab you in the back!====== Unlock Secrets, Reveal Inner Truths ======<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3939410/extras/f2896b8f58976afd8049c6e69ddae9ca.avif?t=1783486336" width=1560 height=878 />Everyone has secrets they guard closely. Find a way to pry them open, and you move closer to the truth! Each “locked heart” represents a key clue. Gather critical clues and connect them to generate new, vital insights. In the end, armed with crucial evidence and your unmatched conversational skills, confront the killer and crack the case!====== Hundreds of Items, Use as Evidence or Gifts ======<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3939410/extras/13dbff20c3e318d227c34608daaaab9f.avif?t=1783486336" width=1560 height=878 />Show your evidence to leave the culprit speechless, exposing every lie! The world is filled with hundreds of items—you can use them as proof or gifts. Give a scalpel to a doctor? He’ll praise you as a kindred spirit. Gift the same to a lady? You might get slapped and scolded, “Are you cursing me?!” AI reacts to each character in real time—blushing, angry, smirking, or even drawing a gun. Flirt or provoke, it’s all about your survival instincts!====== AI Twists! Unlock Multiple Hidden Endings ======<img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/3939410/extras/23a27ad2ca923aff37277349fcd0c72d.avif?t=1783486336" width=1560 height=878 />“Think catching the killer is the end? AI is secretly laughing at your naivety!” Accuse someone of being the murderer? Tomorrow’s headline might read: “Holmes Disgraced! Frame-Up Scandal Revealed.” Hide a key piece of evidence? Ten years later, a mysterious smile from the “late” baron might flash across the street… AI shapes the story based on your words, completed tasks, collected clues, and items, leading to multiple, unpredictable endings. —Shh… did you hear the dogs barking in the swamp?
