I wanna be optimistic and think that you are at your first game dev experiences and decided to use AI as a tool for help. AI is great in helping you get started in something as difficult as game development, but I think it's really important that you use it for the right things. Code creation is great (if you are a beginner, you should still later learn how to code), but put more creative effort in it. The description of the game was clearly AI generated, and I fear the idea too (and if it is not, this is clearly the same as agar.io. Copying games is a good beginning, but maybe not for a game jam).
As someone else said, a comment about the game itself, is that it feels quite boring as the only thing you can do right now is grow big by eating the small circles, and not the other players. I would start the game with more ai players of different sizes to make it more dynamic.
