I may have missed something, and correct me if I am wrong, but to me it seems like you used two examples where parentheses are unnecessary.
I do agree that the music is somewhat repetitive, although I have never really encountered a jam game where the music isnt repetitive in a similar way. Reviewing non-repetitive music as a positive seems more reasonable than reviewing repetitive music as a negative seems more reasonable for me.
I would be pleased if you were to name a game jam game with non-repetitive music.
Please come away with thIS knowing it comes from an amateur critic and a mathematically incompetent mind. Best of luck with your future endeavors.
