Well your game seems to be submitted properly: https://itch.io/jam/godotjam062018/rate/270194
What's missing though is a proper build of the game to download (and if you feel like it, play in the browser, but be aware that there are some issues with HTML5 builds on some browsers).
So are you stuck at the "uploading binaries" step?
(And don't panic, if you don't manage to upload it before the deadline due to technical issues, we'll figure something out.)
