🎮 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]:

{
  "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:

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
