I keep trying to download the game but I can't , why cant it just be already downloaded for you ? The thing I don't get with the process of getting the game up and ready for you to get the full experience of the chosen game, is that where does the file go? do you extract it? move it into somewhere? I really need help with this.
The game cannot update automatically because itch.io is a file-sharing website. It is not an application like Steam that keeps track of your Steam library for you. You need to update the files manually. When you re-download a game that has updated, you need to take the new file, bring it into the folder where the old file is stored, and replace it. Extraction may be necessary with .zip files. Hope you can get everything working!
