UI – Game Menu System

You will need Five menu options (buttons): About, Settings, Roll Character, Play Game [2D and 3D], and Quit. Play Game button should be visible but not be available – until the player finishes Rolling a Character like Project 1A. When a user selects a menu option, your game will load a new unity scene using SceneManager.LoadScene.
