so we know that you have to save the game constantly right? well every time I do save it and I get out of the game and later come back, I can't continue from where I left off. every time I had to start the game from the beginning and it never saves in the save file.  I tried to extract the files from the winrar to my desktop and try again by playing it and then save progress but the same problem still occurs. I don't know if i'm doing something wrong or it's just a glitch for me.

never mind this somehow solved itself a few hours later

First, you need to save the game and then don't press close tab, just go to menu and press game end

that happen to me before
