30 is far more than average. I'd legit say you are in the top 20%. I still rate yours anyway because more is always better.
If you want to you can rate mine https://itch.io/jam/wowie-jam-4/rate/1662496
Oh, i didn't know that but from what I saw the top rated game has 179 ratings, which is a lot.
Very bell curve. Average is 14-15.
