Gemini3-Hackathon-Mystery-Game

Locked-Room Mystery is an AI-native detective game where Google Gemini serves as the Game Master (GM), generating and running unique cases in real time. Core Features Dynamic Generation: Gemini creates a fresh JSON case file (suspects, killer, trick, motive, evidence) and a matching anime-style background image for every playthrough. AI Game Master: Answers the player's freeform questions dynamically. Designated lying NPCs maintain coherent false testimony throughout the interrogation. Contradiction Guard: A secondary AI call cross-checks GM responses against the hidden case data, rewriting inconsistencies to ensure a fair, solvable mystery. Scoring & Feedback: Evaluates final accusations (S/A/B/C rank), highlights logical weaknesses, reveals the truth, and generates a dynamic result screen image reflecting the score's mood. Conversation Summarizer: Distills the Q&A history into a structured deduction sheet to assist the player's reasoning at any time.
