🚀 Key Features

1. Dynamic Time Mechanics

Game ini menggunakan sistem waktu dinamis yang unik dalam educational games:

// Core time management system
const handleAnswer = (userAnswer: number, correctAnswer: number) => {
  if (userAnswer === correctAnswer) {
    setTimeLeft((prev) => prev + 10); // Reward accuracy
    setScore((prev) => prev + level * 10);
    setFeedback("🎉 Benar! +10 detik");
  } else {
    setTimeLeft((prev) => Math.max(0, prev - 4)); // Penalty for mistakes
    setFeedback(`❌ Salah! Jawaban: ${correctAnswer} (-4 detik)`);
  }
};

2. Adaptive Difficulty System

Game secara otomatis menyesuaikan tingkat kesulitan berdasarkan progress pemain:

// Dynamic question generation based on level
const generateQuestion = (level: number): Question => {
  let operators: string[];
  let numberRange: number;

  if (level <= 10) {
    operators = ["+", "-"];
    numberRange = level * 15;
  } else if (level <= 30) {
    operators = ["*", "/"];
    numberRange = level - 5;
  } else {
    operators = ["+", "-", "*", "/"];
    numberRange = level * 25;
  }

  return generateMathProblem(operators, numberRange);
};

3. Real-time Leaderboard System

Live ranking system yang update secara real-time:

// Live leaderboard with auto-refresh
const LiveLeaderboard = ({ gameType = "math" }) => {
  const [leaderboard, setLeaderboard] = useState([]);

  useEffect(() => {
    const interval = setInterval(() => {
      fetchLeaderboard(false); // Silent refresh
    }, 30000); // Update every 30 seconds

    return () => clearInterval(interval);
  }, []);

  return (
    <div className="leaderboard-container">
      {leaderboard.map((player, index) => (
        <PlayerRank key={player.id} rank={index + 1} {...player} />
      ))}
    </div>
  );
};
