A deep underground mine tunnel scene rendered in retro pixel art, featuring massive stone-walled tunnels and a crisscrossing network of old minecart tracks. Warm-toned torchlight illuminates the space, while gold coins are scattered along the path amidst spike traps and fungal obstacles. A blocky snake navigates the tracks, dodging moving minecarts and protruding spikes. Multi-level tracks allow for route detours, with the escape point located at a deep tunnel opening; the dim, atmospheric lighting enhances the sense of adventure, while the track layout becomes increasingly winding, offering a progressive challenge.
