FAQ
How does the text adventure engine work?
Pick a genre (fantasy, sci-fi, mystery, or horror), name your hero, and click Start. The engine narrates an opening scene and offers 2–4 numbered choices. Click a choice (or type a free-text action) and the engine advances the scene, updates your inventory, health, score, and quest flags, and tells the next beat. Four hand-authored template worlds ship built-in; scenes branch and converge, with dice/skill checks where the genre calls for them.
What state does the engine track?
Inventory (named items + descriptions), health (0–100, with optional death/victory thresholds), score (accumulating points), quest flags (boolean switches that unlock branches), current scene id, and a rolling memory summary for long playthroughs. All state lives in localStorage — close the tab and your game persists across sessions.
Can I save and load multiple playthroughs?
Yes. The engine supports multiple named save slots, each storing the full game state plus a transcript of every scene + choice so far. List saves, load any one, delete old ones, and export a playthrough transcript as plain text or Markdown. History (your last 20 game-overs or victories) is tracked separately so you can回顾 past runs.

Is my data sent anywhere?
No. All scene narration, branching, state tracking, dice rolls, save/load, and transcript export run locally in your browser. Your playthrough stays on this device. The only network call is if you paste your own LLM API key and click 'Enhance narration' — that request goes directly from your browser to the LLM provider you choose.
