First, dont lie you have 10 ratings.
Second, if you want me to rate just ask dont lie!
There's 2 different ratings, ratings for the game jam only show on your submission page.
The ratings you see in your project info are the normal ratings for any game on itch.
You can play any game outside of a game jam and give it a rating but it's a different system and doesn't have the option categories that are set up for rating games in a jam.
If you got the submission page for the project you should the number of ratings just above the project info on the right.
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.
