Game Features
- Live LLM Narrative — Every scene, every reply, and every character — Light, L, and Ryuk — is written in real time by an LLM as you play. No two investigations unfold the same (deepseek-chat real-time narrative).
- Moral Choice System — Write a name or close the notebook. Justify every kill or hesitate. Suspicion and Conviction climb and fall with every decision you make.
- The First Trap — L broadcasts a live challenge to Kira, daring him to answer. How you respond decides whether the world's greatest detective closes in — or walks right past you.
- Investigation Counter-Play — Careful, bold, righteous, or deceptive: every move feeds L's suspicion meters and shapes how the case unfolds around you.
- Multiple Endings — From a hesitant hand that never writes a name to a god of the new world caught in the first checkmate — the ending is built from every choice you make.
- Browser Playable — Runs directly in your browser, no download needed. Live LLM dialogue on every page turn.
Character Sprites
Production Process Breakdown
AI receives the prompt "Create a Death Note world where a notebook kills anyone whose name is written in it — a duel of intellect between a student who becomes a god and the world's greatest detective" and generates the Death Note world — 21 atom cards: characters (6), locations (4), events (5), items (3), rules (3). Each card contains original descriptions, cover art, and interconnections.
AI designs the game from atom cards: writes story rules, designs scene flow, generates all art assets (title background + scene backgrounds) and the character sprites. Each sprite was generated with a full-body sprite prompt, then background-removed to transparent PNG via BiRefNet.
Game built and published with one click, instantly shareable online. A live LLM (deepseek-chat) improvises dialogue in each character's voice — Light, L, and Ryuk — as you play.
