I just checked it, and it seems I didn't clear the screen after the fight in this version. So, no, there isn't a way around it. "Technically" there is a way to beat the build as the only thing this does is cover the vision, but that's like asking a monkey to type shakespeare thru a typewrite "It's technically not impossible".
SO! I made a bug fix, I uploaded a special build named "Version 0.1.2" which fixes that bug., so just download that, copy your save folder and paste that in.
