夜の丘の上の不気味なドット絵の幽霊屋敷

Create a pixel art image of a spooky nighttime scene. The centerpiece is a black haunted house with glowing windows, perched on a hill. Next to it stands a leafless tree with twisted branches. In the background, cemetery crosses are visible under a dark purple sky. A bright yellow full moon shines intensely, surrounded by tiny star-like sparkles. Use a limited color palette of purple, black, and yellow to enhance the eerie Halloween atmosphere. Apply dithering and low-resolution details to emphasize the pixel art style, with crisp edges and minimal shading for a retro feel. Avoid gradients, opting for flat colors and intentional pixel clusters to maintain authenticity.
