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. Background sky layer. A night sky with a cold full moon placed high in the middle of the image, slightly right of centre and well away from every edge and corner, thin drifting clouds and a few stars. Along the lower half, three layers of distant mountain ridges fade into blue mist. Nothing stands in the foreground and the bottom edge is plain mist.
