Twenty-forty-eight

It is April 2014, and the popular game "2048" has not yet been released. Your task is to implement the game before the official release. The objective of the game is to slide numbered tiles on a grid to combine them and create a tile with the number 2048.

Instructions

To complete this exercise, you will need to do the following:

• Create the 4x4 grid and fill it with tiles valued at either 2 or 4.
• The game must start with 3-4 tiles randomly placed on the board.
• Implement the ability for players to swipe the tiles in any of the four directions and have them move as far as possible in the chosen direction.
• Use animation to smoothly move the tiles. You are free to choose the colors for the tiles.
• If two tiles with the same value collide, they should merge into one tile with twice the value, and the score must be updated accordingly.
• After each move, a new tile must appear randomly in an empty slot on the board.
• The game ends when no legal moves are possible (i.e., the grid is full, and no adjacent tiles have the same value).
• You must add a restart button so that the player can restart the game and try to achieve a higher score.
• Include functionality to track and display the current and best scores live during gameplay.
• Update the best score if necessary when the game is over.

Remember to follow best practices for coding and game development, and be sure to document your code and any decisions made during the development process.

Bonus

To enhance the game, you can consider implementing the following features:

• Design a user interface (UI) for the game, including buttons for moving the tiles and displaying scores.
• Add difficulty levels or additional gameplay options, such as the ability to choose tile values (e.g. 2, 4, 8, ...) or customize the grid size (e.g. 4x4, 5x5, 6x6, ...).
• Incorporate sound effects or background music to improve the gameplay experience.
• Ensure the game is responsive and supports different devices and screen sizes.
