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. A long strip seen straight from the side, occupying only the bottom third and running edge to edge at an even height: reeds and muddy river bank with moored boat hulls and rope. The bottom is a straight line of mud. The background is one plain solid magenta colour (#ff00ff) with nothing else in it, for chroma keying.
