Pixel art scene in the style of a classic retro platformer world inspired by Mario games: blocky green hills, brick platforms, question-block-like shapes, small clouds, and a warm golden-hour yellow sky. In the foreground, a cute pixel-art cat character standing on a platform, holding a sign. The sign clearly displays the exact text on two lines: "สวัสดีค้าบอ้วง" and "Hello Human". Charming, colorful, nostalgic 16-bit video game aesthetic, crisp pixel edges, playful composition, warm lighting.
