This is my first jam and I already hate this things. Even I started playing and rating games with least ratings. I felt very sad to see that for many good ones I was the first or second person to rate. Especially for those people for whom it was their first game jam.☹️
I think it is crucial to get honest feedbacks from as many people as possible so that we can improve. I think only those accounts should be allowed to rate a game who have submitted a game in the jam.
