Final Product: Death Note: First Judgment
Death Note: First Judgment is a playable interactive visual novel set in the world of Death Note. You are Light Yagami — a top student holding a notebook that should not exist. Write a name and someone dies. The shinigami Ryuk watches from the shadows, amused. And the world's greatest detective answers with a televised trap that could unmask you in the first move.
The story is written live as you play. Test the notebook on a known criminal, answer L's bait boldly, or stay quiet and observe — type any action and the LLM narrates the scene in Light's voice, in the cel-shaded black-white-crimson aesthetic of the anime. Every choice shapes suspicion, conviction, and whether Light becomes Kira… or gets caught in the first move.

Game Features
- Live LLM Narrative — Every scene, every line of inner monologue, and every shinigami or detective reply is written in real time by an LLM as you play. Light's calculation, Ryuk's amusement, and L's quiet trap all arrive in the moment — no two first judgments unfold the same (deepseek-v4-flash real-time narrative).
- Type-Anything Gameplay — Instead of fixed dialogue trees, type your next move: “open the notebook and read its rules”, “write the name of a wanted criminal”, “hide it and say nothing”. The story answers in Light's voice with real consequences on the page.
- The Death Note Cast — Light Yagami, the detective L, and the shinigami Ryuk appear as full-body anime sprites in the classic Death Note aesthetic: cel shading, sharp shadows, flat color. From neutral composure to smug genius to wide-eyed shock — the faces of the first judgment.
- Suspicion & Conviction Meter — A live meter tracks how close Light is to becoming Kira — and how close the world is to unmasking him. Every typed action feeds suspicion and conviction, and the ending of the first trap shifts with how boldly you play.
- Death Note Aesthetic — Every background and sprite is rendered in a limited black-white-crimson palette: Light's bedroom at night, the glowing TV news room, the empty classroom, the Tokyo skyline under a blood-red moon.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every page turn — start the game and write your first judgment.
Character Sprites
Production Process Breakdown
AI receives the prompt and generates the Death Note world — 21 atom cards: characters (6: Light, L, Ryuk, Misa, Near, Mello), locations (4), events (5), items (3), rules (3). Each card carries original descriptions, cover art, and interconnections across the investigation.
AI designs the game from atom cards: writes the prologue story rules, the scene flow from the falling notebook to L's televised trap, and generates every art asset — 4 scene backgrounds, the title key art, and 5 character sprites. Each sprite was generated with a full-body sprite prompt on a pure white matte, then background-removed to transparent PNG.
Game built and published with one click, instantly shareable online. The live LLM (deepseek-v4-flash) improvises Light's first judgment in real time as you play — narrating scenes, voicing Ryuk and L, and reacting to every action you type.
