There a bug in my game that prevents you from killing a boss does anyone have any idea how I can get it resubmitted to fix this error cause its actually unplayable right now
I think in the context of the jam you are not allowed to upload anything past submission, although once it ends you can add bug fixes and allow some to still play it.
You could create another itch page and link it to the submission page (Some have done so), but that is cheating and people would only rate on what is available on the original itch page.
