feat: Expand Quiz Categories and Implement Comprehensive Question Bank with Difficulty Levels

[smirk-dev]

🎯 Feature Description

Currently, QuizzyArcade only includes 2 quiz categories (HTML Mastery and JavaScript Ninja) with 2 questions each. The data/games.jsx file even has a comment indicating more games should be added: // Add 4–6 more quiz games...

This feature request proposes to significantly expand the quiz content by:

1. Adding 4-6 new diverse quiz categories
2. Increasing questions per category to 8-10 for a more engaging experience
3. Implementing a difficulty level system (Easy, Medium, Hard)
4. Enhancing the data structure to support better quiz mechanics

🔍 Problem Statement

Current Issues:

• Limited Content: Only 2 categories with 2 questions each makes the app feel incomplete
• Poor Replayability: Users can exhaust all content in under 2 minutes
• No Difficulty Progression: All questions are treated equally, no challenge scaling
• Incomplete Implementation: The comment in games.jsx shows this was intended but never completed
• Missed Gamification Opportunity: No way to track difficulty achievements or progression

User Impact:

• New users might think the app is a demo/incomplete
• No incentive to return after completing all quizzes
• The "arcade" feel is diminished without variety and progression

✨ Proposed Solution

1. New Quiz Categories (Add 4-6 of these):

• CSS Wizard - CSS selectors, flexbox, grid, animations
• React Fundamentals - Hooks, components, props, state management
• Git & GitHub Pro - Version control, branching, pull requests
• Web Security Essentials - OWASP, XSS, CSRF, authentication
• Node.js Backend - Express, middleware, REST APIs
• TypeScript Mastery - Types, interfaces, generics
• Algorithm Challenge - Big O, data structures, problem-solving
• Database Fundamentals - SQL, NoSQL, queries

2. Enhanced Data Structure:

export const games = [
  {
    id: 'html',
    title: 'HTML Mastery',
    icon: 'code-slash-outline', // Ionicons name
    color: '#E34C26', // HTML orange
    difficulty: 'easy',
    questions: [
      {
        question: 'What does HTML stand for?',
        options: [
          'Hyper Trainer Marking Language',
          'HyperText Markup Language',
          'HighText Machine Language',
          'Hyperlinks and Text Markup Language'
        ],
        correctAnswer: 'HyperText Markup Language',
        difficulty: 'easy',
        explanation: 'HTML stands for HyperText Markup Language, the standard language for creating web pages.'
      },
      // 7-9 more questions...
    ],
  },
  // More categories...
];

3. New Features to Support:

• Difficulty Badges: Display difficulty level on GameCard component
• Progress Tracking: Show X/Y quizzes completed per difficulty
• Explanations: Show correct answer explanation after answering (optional)
• Category Icons & Colors: Visual differentiation between categories
• Question Randomization: Shuffle questions and options for replayability

📋 Implementation Checklist

• Add explanations for educational value

Phase 2: Component Updates

• Update GameCard.jsx to display category icon and difficulty badge
• Modify QuizQuestion.jsx to show difficulty indicator
• Add optional explanation display after answer submission
