Pixel art for a dark 2D side-scrolling action game set in China's Three Kingdoms era, around 200 AD. Muted low-saturation palette of dark blues, slate greys and earth browns with very small dull red accents. Large crisp pixels, flat shading, no characters, no people, no text, no UI. Middle-distance scenery seen from the side, filling only the lower half and running the full width: a night road past a ruined village, broken walls, dead trees, a collapsed well and a leaning shrine gate. Dim and bluish, seen through haze. The background is one plain solid magenta colour (#ff00ff) with nothing else in it, for chroma keying.
