"Design a modern, 16-bit pixel art-inspired feature showcase page for the ‘Healthy Eating Challenge’ app. The page should highlight key features like meal reminders, Nutri-Score grading, and group challenges, all presented through vibrant, pixelated graphics. Include playful, retro-style characters interacting with food items, scoring systems, and competition elements, while maintaining a clean, user-friendly layout. The overall design should blend nostalgic gaming aesthetics with a contemporary focus on foodtech, emphasizing the app’s purpose and functionality in a fun and engaging way."
