title: 2D Game Development "God class"
body: <p>I am developing a 2D game in C++ using SFML API, but I am having an issue with class design.
  I think that I am disobeying the SRP (Single Responsibility Principle) because I have one main class called "Game" that should handle the window. It contains a method containing main game loop.
  Now the problem; it contains object (composition) of more than 5 classes, such as Player, Menu, SplashScreen.
  Do you think that it is a good idea to create such "God" class? Do you know any open source C++ 2D games from which I could learn?
  Thank you in advance.</p>
