I wonder the same thing. I wanted to re-upload an audio file because then I noticed a couple of mixing details that I'd rather fix that no one's really going to notice so it's not worth it, but it wouldn't be any significant change really. I would understand that it wouldn't be fair or possible to be able to do that, I won't, but I would also like to know if it's possible to add more detail or development to my submission regarding the imaginary game and what I did and all that.
