I established the art direction by designing a high-contrast, dark-ambient environment that captures a street basketball aesthetic. The UI utilizes custom graffiti typography, spray-paint textures, and a thematic NBA color palette, featuring interactive components like hover-state illuminated buttons. My role spanned the full design lifecycle, from wireframing the registration and social sharing flows to crafting the complete gameplay UI, including synchronized animations for loading states and real-time interactions.

To ensure a seamless user experience, I conducted targeted usability testing on lobby creation, invitation flows, and core gameplay performance. This process focused on optimizing animation fluidity, minimizing latency, and validating the real-time ranking system to maintain high user engagement and functional reliability.
