Hi, your GitHub is missing the Packages folder. I mentioned this in my message 3 days ago. I will give you 24 hours to update your source, otherwise I will have to remove your submission for not uploading all of your source.
If using Unity, delete the Library folder, and then zip up the rest. It should look something like this: https://github.com/rpie3/a-friend-in-the-end
You can just upload this as a zip to your game page.
Yep, it looks good now. Use this link to add your game back to the jam: https://itch.io/jam/318018/add-game/1554629?token=2s5SA76CIxBsS07dAGjyk5TK8
