could you get it fixed, and if yes, how?
I'm sorry to hear that. Maybe if you'd like to save directly before that error and attach this save file (version 0.1.2.3 Windows) here, I can try to skip the critical scene on my computer, save and send file back to you... Though, I can't make promises whether it will actually work.
BTW (very little spoiler): You won't miss anything important - after the display flickering and the white shadow some laughter came and hero wonders asking himself about the origin of it. Thats it.
