- Moved confetti from Game() to a specialized container. Will see if I can modify the FadeIn() class so that they both inherit from the same Animation() class.
- The wingding container is now a part of the middle-ground animations for the win-screen (animations can be in back-, middle-, or fore- grounds).
- Coupled sequence logic to game state in main() to help with the refactor.
- Turned the "Press any key to continue" message on the win and retire screens into buttons. Now pressing a key or clicking on the message changes state.
