Create a pixel art dungeon scene as a tileset with tiles measuring 32x32 pixels. Include various elements such as moss-covered stone walls, ancient stone floors with cracked tiles, eerie glowing runes, scattered bones, rusty chains, cobwebs, and flickering torches on the walls. Incorporate treasure chests, dungeon doors, and traps like spikes and pits. Design each tile to seamlessly connect with adjacent pieces, ensuring a cohesive and immersive dungeon environment. Do not add any lighting.
