New Feature: Combo System

The new update introduces a "Combo Multiplier" system to the color matching game, enhancing the gameplay experience by rewarding consecutive correct guesses. Here's an explanation of how this update works:

1. **Combo Multiplier Mechanism**:

   - The game now includes a combo multiplier, which increases by 1 for each consecutive correct guess made by the player.

   - This multiplier is displayed under the score and streak, showing the current multiplier value as "Combo: x[number]".

2. **Scoring with Combo Multiplier**:

   - When the player makes a correct guess, the score is increased by an amount equal to the current combo multiplier.

   - For example, if the combo multiplier is 3 and the player makes a correct guess, they gain 3 points instead of just 1.

3. **Resetting the Combo Multiplier**:

   - If the player makes an incorrect guess, the combo multiplier is reset to 1, regardless of its previous value.

   - This reset adds a layer of challenge, as maintaining a high combo multiplier requires consistent accuracy.

4. **Impact on Gameplay**:

   - The addition of the combo multiplier encourages players to focus and strive for consecutive correct guesses to maximize their score.

   - It adds an extra layer of excitement and challenge, especially for players aiming for high scores.

5. **Visual and Audio Feedback**:

   - Along with the score update, the game continues to provide visual confetti effects and audio feedback for correct and incorrect guesses, enhancing player engagement.

6. **Integration with Existing Features**:

   - This new combo system is seamlessly integrated with the existing features like the difficulty level selection, timer, high score tracking, and color generation mechanics.

By implementing the combo multiplier, the game not only becomes more engaging but also rewards skillful play, encouraging players to improve their performance over time. This feature aims to keep players motivated and adds a competitive edge to the game.
