The underground tunnel network

Generated from: Wide side-scrolling underground tunnel environment, rough hewn rock walls with water dripping down in streams, multiple branching passages visible at different heights connected by wooden ladders and crumbling ledges, pools of stagnant glowing water on the ground floor, hanging exposed roots from the ceiling, rusted metal pipes running along the walls, a collapsed section blocking one passage requiring a detour, a distant light source deep in the tunnel casting long shadows, small creature burrow holes in the walls, wooden support beams holding up sections of the ceiling, dark palette of charcoal grey and deep brown with cold blue water reflections Drawn in this game's art direction: Hand-drawn 2D illustration with premium detail, painterly textures on every surface, no cel shading, realistic volumetric shadows and soft rim lighting, rain and fog atmospheric overlays, a dark cinematic palette dominated by deep blue-blacks and charcoal with selective warm amber and sickly green accent lighting, wide-format compositions with strong foreground-to-background depth layers, moody horror atmosphere throughout Everything is original: never draw or resemble characters, places or logos from existing games, films or brands (no red-capped plumbers, no famous mascots), even when the idea names one: take a named game's look and mood, never its characters, names or logos. No text, UI, HUD, logos or editor screens inside any image.
