===================
This function controls the flow between states of the game.
It loads previous saved games, setup levels states, controls the
flow between levels, including when player loses or when completes the game,
and checks if the result of the current game is a highscore.
The "real" game loop (player actions in like moving, killing, etc.) is in the
PlayLoop function.
