THE BACKGROUND

Online Go Server Redesign
What is Go?
Go (also called Baduk 바둑 in Korea) is a two-player strategy board game where the goal is to control more territory than your opponent by placing stones on a grid.
Overview
Online Go Server (OGS) is a global platform for Go players to connect and compete. Despite its strong community, the platform struggled with usability challenges, outdated UI, and inconsistent experiences across devices. This project aimed to enhance user engagement, streamline navigation, and modernize the overall design.

You're showing only the cluttered UI with annotations, but there's no side-by-side “After” UI screen to highlight the improvements you implemented.
Image Is Overwhelming Without Context
The image has a lot of red annotations (like “Clickable indicator”, “Quick links”, “System notification”), but it’s unclear whether this is the before or after state.
