So it turns out that the reason I haven't been able to get farther in Bloodstained is that a patch caused the chest that was supposed to have the silver bromide to be pre-opened, which means that I can't get my picture taken, which means that I can't get a fake ID from the vampire librarian, which means I can't board the train to the next area. Options are to start over or to uninstall/reinstall and never let it get patched.
