Hello!
I think it would be a good idea to add a sorting option on the game jam submission page that sorts based on how I personally rated them. This could mean having unique sorting options for each rating category, but it probably would be less obtuse to just have one option that sorts based on the average number of stars in each category. The rationale here is that, when I'm rating a large number of submissions, it's hard to be sure I'm rating things consistently, and being able to go back and see if there are any particular submissions that seem to be out of place relative to the others would be super nice.
Also, I'd like to say that the sorting functions on jam pages are already phenomenal as is - this is just a pretty small quality of life thing that I think would work well.
Thanks! - Aidan
