## 🎮 GBA Controller Overlay

On mobile, a semi-transparent Game Boy Advance-style controller overlays the bottom of the screen:

| Control | Action |
|---|---|
| **D-pad** | Walk the player around the map |
| **A button** (red) | Talk to NPC on map · Confirm answer in battle · Advance dialog |
| **B button** (blue) | Talk to NPC on map · Advance dialog |
| **SELECT / START** | Decorative — reserved for future use |

The controller is hidden on desktop (≥900px wide) — use the keyboard instead.

---

## ⌨️ PC Keyboard Controls

| Key | Action |
|---|---|
| **WASD / Arrow keys** | Walk player on map |
| **E / Enter** | Talk to NPC · Confirm answer · Advance dialog |
| **X** | Talk to NPC · Advance dialog |
| **1 / 2 / 3 / 4** | Quick-pick answer directly |
| **Space** | Advance dialog |

---

## 🗺️ Map & Walking

- The player sprite walks freely around the overworld map using the D-pad or WASD
- Walking animations change based on direction (left, right, up, down)
- Press **A**, **B**, **E**, or **Enter** at any time to talk to the NPC and start the question
- Tapping the NPC sprite directly also triggers the conversation

---

## 💾 Save System

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

- **Auto-saves** after every answered question and on map return — a 💾 icon flashes to confirm
- **Continue screen** appears on next visit showing trainer name, progress %, and score
- **New Game** option always available — prompts confirmation before erasing save
- Save clears automatically on completion so the next run starts fresh

## ➕ 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 in the `options` array (0 = first option, 1 = second, etc.). The game shuffles the display order randomly at runtime, so the position shown to the player will vary each time.

---

## 🧑 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`.

## 📱 Mobile Tips

- Add to Home Screen on iOS/Android for a full-screen app-like experience
- The game uses `100dvh` and `env(safe-area-inset-bottom)` for notched phones (iPhone X+)
- Tap anywhere on the dialog box during the intro to skip the typewriter and advance
- Tap the NPC sprite directly on the map as an alternative to pressing A/B
