So, a couple things I noticed:
1. You submitted a whole Unity project, not a build of any game.
2. There isn't much of anything in the Unity project. No art assets, no scripts, and only a SampleScene. And while I can't open the Unity project (I don't have this project's version downloaded), a quick glance makes it appear that said SampleScene has had little to no changes.
I don't know if something happened on your end, but I'm not going to rate it, since there's nothing to actually rate.
