Phantom Child when switching game state

[alycda]

I thought I would be clever with nested gamestates and found that my idea would not work as expected (can't do GameState::Game(_) to match all variants of an enum.

I added a return to menu keypress and found that the player remains on screen even though it is scoped. see this forked branch: alycda@2014360
