It sounds like most people who claim they can’t play haven’t really been on itch.io before. The file needs to be unzipped via downloading the winrar zip application. (google it)
From there download the game, unzip the file, and in the folder click the “game” application and you’re golden.
My issue was that I did not have a gothic font. Thankfully the creator added the fonts in the folder for installation. Very quick process and only really took me a minute to figure out.
