type GameEvents = {
  'player:hit': (damage: number) => void;
  'game:over': () => void;
  'score:change': (score: number, combo: number) => void;
};

const events = new EventEmitter<GameEvents>();

// Subscribe
events.on('player:hit', (dmg) => console.log(`Hit for ${dmg}`));
events.once('game:over', () => showGameOver());

// Emit
events.emit('player:hit', 10);
events.emit('score:change', 100, 3);
