MiniGame Menu Screen

Overview

The MiniGameMenuScreen class provides players with a menu to select among various mini-games, including Snake, BirdieDash and Under-water maze mini games. Players can choose to play any mini-games or navigate back to the main menu for the main game. This screen utilises LibGDX's Scene2D module for managing UI elements and handling user input.
