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.

    See this thread on the Gamedev site about God classes (yes, they are a bad idea because tight coupling makes code less robust in the face of change).

    Don’t know about 2D, but there is a whole GitHub repo with id-Software 3D game engines. Apart from the graphics, this should provide a treasure trove for you. See also the Doom source code review for ideas on good coding style for writing games.
