Ooh no, I know!
My feedback style is to focus on some very specific actionable items to help you focus your efforts for further work or for the next thing.
I really hope I'm not discouraging. You are where everyone starts. A finished game IS a big deal!There is no better way to improve as much as game jams. If you do 5 or 6 in a year, by the end of it you will be so much better than if you were to work on only one thing during that time. Jams let you have feedback, see what other people do, test out something, and develop your sense of how much time scope takes.
Each jam gets easier, because you have a history of things you've finished, and can hone your ideas and techniques. The tools and techniques now verses 10 years ago has really improved in the indie dev scene.
You are at an exciting start!
