Yeah, it's something that the Itch uploader does randomly and I have no control over it - sorry!
It's very easy to extract, though. Doesn't matter what generation your phone is - the extraction is done via app (such as Google's own: https://support.google.com/files/answer/9048509?hl=en-GB ) and so your phone can handle it. Plus, zip files are almost as old as the internet so you could extract it on a potato ;P
