I believe the game has a save feature that will allow me to restart it later at the point where I left off. But I can't figure out how to use it. Can you help?
You can enter the menu (for example by using right click or pressing Escape) and save/load there (click on the squares to save/load). Some of the slots on the top left are a little bit buggy I've noticed, so try saving and loading using other slots if it's not working.
Thanks for your help. I was able to set some save points. But I'm thrown off by the commands "Load Save File" and "Overwrite Your Save File." Would you explain what each of them does?
Load save file is what you use to continue from whatever save point you select. Overwrite save file means you replace an existing save point with a new one.
