itch.io

Yes it is a video format, some websites allow you to use video files how you would normally use a gif in page content by adding the tags playsinline, autoplay, muted, and looping to the video element. https://developer.chrome.com/docs/lighthouse/performance/efficient-animated-cont...

I have tried just adding the html video tag myself but while it seems to work ok in the edit view of the page, it doesn't quite work on the project view of the page, and when I try to add it as a video itch embeds it in an iframe that needs to be clicked which isn't what I want either.
