Saving and Checkpoint System

Time to give flexibility to the user to play the game moreeasily. As the game is becoming bigger, it becomes annoying when game starts everytime from the beginning. We were needing some sort of system to save the game data and load it back once the game starts. This was the most interesting task in the game. We could have done by simply pre-setting data which needs to be saved; but the problem with this approach is that everytime one has to update that list which wouldn't be best approach. I created an API so that anyone can call the API to save any sort of data and get it back after the game starts.
