Escenario de Desplazamiento Lateral de Bosque a Cueva

A wide horizontal 2D side-scrolling beat-em-up game background stage showing a seamless transition from an enchanted forest into a dark cavern, side-view panoramic composition with parallax-friendly horizontal layering. The foreground features a continuous flat walkway stretching across the bottom third, constructed of exactly 9 large decorative stone tiles, each featuring an oval medallion with a stylized leaf or flower motif, separated by thin grout lines, with a narrow strip of grass along the very bottom edge. On the left half, a dense forest unfolds with tall slender tree trunks in vertical rows, a mossy leafy canopy hanging from the top, and layered undergrowth fading into soft green atmospheric shadows. At the center-right, a massive ancient gnarled tree trunk forms the natural transition boundary, its thick roots and bark organically merging into the cave entrance. On the right half, a dim cavern interior displays dark textured rock walls, stalactites hanging from the ceiling, and stalagmites along the floor, receding into deep charcoal darkness while maintaining the continuous level floor. Visual style: [hand-painted 2D fantasy game background] with soft dusty lighting and subtle edge vignetting; mood: [quiet mysterious forest-to-cave transition]; color palette: [muted moss green, sepia brown, dark charcoal cave shadows, pale stone]. No characters, no UI, no text.
