I had some troubles with this, but after looking at the console I saw what was wrong
If you looked at this, you might see nothing wrong
It works normally, right? Yes. Itch.io, doesnt want this though
It does not allow HTTP links. But this site, is actually an https but the person advertising it that I found, accidentally left it http. It worked fine, but not for itchio. Here is the fixed version
<sciprt src="<a href=" https:="" raw.githubusercontent.com="" wilq32="" jqueryrotate="" master="" jqueryrotate.js"=""></sciprt><script src="https://raw.githubusercontent.com/wilq32/jqueryrotate/master/jQueryRotate.js"></script>
Also you might need to use a file entirely for itchio! Hope this helped!
