If you go to https://itch.io/jam/code-for-a-cause/entries directly you can see it does exist but has been hidden until the deadline. I guess otherwise, early submissions would get rated more and have an advantage maybe.

As TeaHands said, we keep them hidden until the jam ends to have more fair ratings! We also carefully review and remove submissions that break the rules. You can still ask for feedback from other jammers over on the Discord!
