Also, for any game that has a save system, you can also save your game from the site and resume it after coming back to the page.
To do this, while in-game, click the button at the bottom of the game window labeled "Save State" and another window will pop up
prompting you to select a save location. You can put this anywhere as long as you can find it again. When you come back to the game,
inside the game window, there will be an option right next to the "Save State" button called "Load State". Click that button,
and choose the file you saved on your PC. This will allow you to continue where you left off. Happy Gaming!
