Added all features and Improved UI

[Kavin56]

This pull request introduces several key enhancements to the game.

1. Single Player Mode: Now players can enjoy challenging solo gameplay against an AI opponent with adjustable difficulty levels. This feature adds depth and engagement to the game, allowing users to test their skills in a variety of scenarios.

2. Multiplayer Mode: With the addition of multiplayer functionality, users can now compete against friends or family on the same device, fostering a sense of camaraderie and healthy competition. This feature enhances the social aspect of the game, making it more enjoyable to play with others.

3. Customizable Grid: One size doesn't fit all, which is why we've included the option to customize the grid size (rows and columns) before starting a game. This flexibility allows users to tailor the game to their preferences and skill level, providing a more personalized gaming experience.

4. Score Tracking: Keep track of your progress with our integrated score tracking system. Now players can monitor their performance throughout the game, providing motivation to improve and compete for high scores.

These enhancements have been carefully implemented and tested to ensure seamless integration and optimal performance. I'm excited to contribute these improvements to the project and help elevate the gaming experience for our users.
