In a game jam people normally only rate the game for the jam.
If you wanted to get general ratings as well, you would either need to produce the perfect game that people would be willing to pay for, or spend a lot of time and effort on marketing your game to the wider public.
For most people a game jam is about the experience, not money or fame.
No offence intended.
It's a part of the game jam system that isn't very well explained, it confused me for a bit in my first game jam as well.
How my dashboard said no ratings yet my game jam page said I had ratings submitted.
What I realised was that when you rate a game in the jam, the rating categories can be defined by the jam host and are specific to the game jam in question.
These also don't show on the dashboard because they are specific to the jam and could be defined as anything from how nice the art and game play is, to how many times a ball bounced.
If someone rates your game on the game page, this is for the main itch.io ratings that are global across the platform. These are the ratings that will show on your dashboard, but they are not configured into the categories that can be used within the game jam rating system and won't be able to tell you anything that can help you improve.
