Added another mainloop to enable the choice of another mode

Is there any way we get to quit to change from one mode to another? I had to quit the game to do so.

Sure I could make a change to it so that when you chose not to have another round, it goes back to the game mode option with the option to quit the game from there.

Very cool, thank you for sharing this! I've learned a few new concepts just reading through the code and figuring out how it works.

I have added the requested functionality
