If I were to report a bug it would be.... the fact that you can dominate the red, the blue, etc. To get their artifact and the weapon it makes, without killing them.
Most of the casualties were women and children. Also Russian. Between 13% and 15% of the U.S.S.R.'s total population (not just military) died in the second World War.
Pretty good. I'd say, however, that the massive spiderweb of panels once you're finished might could form some sort of image, like, perhaps, a duck. And definitely some sound effects and BGM. (It'd be awesome if the music changed based on the story of the duck you were working through)
