How to play:
🏚️ Herd all animals into the barn to win.
🖱️ Click a tile to place a wall — answer a vocab question first.
✅ Correct answer → wall placed, animals reroute.
❌ Wrong answer → a random wall disappears instead.
🔄 Switch to Remove mode to tear down a wall (costs a question).
🐾 Animals roam randomly and avoid walls automatically.
