Hello, so I'm taking a look at the zip file but it's different from other games mainly because I can't seem to find the file that will download the actual game

There seems to be some confusion as neither this game nor the community host any downloaders; the files you download manually are the ones you get. Itch.io has an app which is a downloader and will install the game for you. Otherwise you can download the zip file, extract it into it's own folder, and run it from anywhere on your computer that does not have restrictive folder permissions.
