Consider a real-world example of the Memento design pattern for Video Game Save System. In video games, players often have the ability to save their progress and later load it to continue playing from where they left off. The Memento design pattern can be used to implement a robust and flexible save system that allows players to store and restore their game states. Consider following constraints to implement this design pattern:-
a. Saving the progress of the game at any point
b. Undo or redo actions within a limited number of steps
c. Game modes: single-player or multiplayer
d. Game progress
e. Save frequency, validation, size limit and compatibility
