I agree that a close to 20 ratings tab would be a good idea, especially here close to the deadline. But I also often feeling bad for some of the games that nearly gets no feedback or ratings. Especially for them that have made a good game, but just not made any marketing or forgot to give feedback on others games.
I also believe for this kind of jam, with a lot of new jammers, there needs to be more help with how to upload a games correctly. I see way too many people only uploading a .exe file, or making a web version that for some reason is not working. And please upload a Cover image and some screenshots.
