I tend to be quite lenient with most projects. This is a local 48-hour jam, and within such a short time, it's physically difficult to create something truly polished and deeply refined. But what I do want to see are ideas.
Dude, I have nothing against using free assets. But whenever I recognize them, I immediately start judging the project much more critically. It makes me ask: What was the saved time used for? What is the final value of this project? Does it convey any unique idea?
I respect that you participated in the jam and managed to complete a project. I hope that in the future, your games will have more interesting ideas.
Good luck with your future projects—keep searching and experimenting!
