## 💾 Save System

Progress is stored in the player's browser (`localStorage`) automatically:

- **Auto-saves** after every answered question and on map return
- **Continue screen** appears on next visit if an in-progress save exists
- Displays trainer name, question progress, and score on the continue screen
- **New Game** option is always available (prompts confirmation to prevent accidents)
- Save is cleared on game completion — ready for a fresh run

## ➕ Adding Questions

Edit `questions.json`, add to the `questions` array inside `levels[0]`:

```json
{
  "id": 101,
  "npc": "Professor Oak",
  "text": "Your question here?",
  "options": ["Option A", "Option B", "Option C", "Option D"],
  "answer": 0,
  "explanation": "Why Option A is correct."
}
```

`answer` is the **0-based index** of the correct option (0 = A, 1 = B, 2 = C, 3 = D).

---

## 🧑 Adding NPCs

In `game.js`, add to the `NPC` object at the top:

```js
const NPC = {
  'Your NPC Name': '🧑',
  ...
};
```

Then reference `"npc": "Your NPC Name"` in `questions.json`.
