Don't hesitate to contact the jam organizers so you can upload your fixes here if that hasn't happened yet!
I've done so multiple times for this jam, but I do know the hesitation. But working on these games so much, it doesn't make sense to have a large part of the content you and your team painstakingly created not be playable.
Like, I did not see anybody who had a cutscene playing in their title screen, so it's clear you guys loved this project.
