In my Godot C module, I have some code in a header file that looks something like this:

namespace CompanyName
{

namespace GameName
{

namespace Actors
{

class Character
{
    //...
};

};

};

};

I'm a little worried that this is too many namespaces, and the class name will be to difficult to type out because of it. (CompanyName::GameName::Actors::Character would have to be everywhere the class is used)

On the other hand, I need these namespaces to differentiate my code from third party code, this particular game's code from the code of one of my other games, and this specific part of the game's code from other parts of its code.

Which namespaces should I leave out (if any at all)?
