So on the submission page at https://itch.io/jam/cgj/entries the standard sorting is by "Random".
If you change that to "Most Karma" the games will be sorted by who gave the most ratings.
I'm currently ranked at #12 with 70 games rated, so every further up that list that has given more ratings. Some of those games on the other hand did even receive 20 rating. Some of them not even 10.
So go rate their games and leave a comment and you will likely hear back from them.
