It's horrible, but I was too far in by the time I finalised the temporal dithering to have any options other than binning all the art, or switching to monochrome. I muted the palette, and that helped, in the game at least. The other screens flicker violently and were added later.
I think the disparity was due to the palette getting tuned for the existing art, once I saw the state the original palette (bold, contrasting) made of it. This was before I drew intermediate scenes/screens. I can't say they are all bad, but the game itself was tolerable to look at, for the length of a game.
