Kaitlyyn Ethylia developed the MomentumBar feature for the Wynntils/Wynntils repository, focusing on real-time momentum visualization within the game. Using Java and applying principles of UI design and overlay management, Kaitlyyn implemented functions to calculate and display momentum and its percentage, providing users with immediate feedback on their in-game status. The work included enhancements to code organization and styling, ensuring maintainability and clarity. By integrating real-time overlays, Kaitlyyn addressed the need for intuitive game state visualization, directly supporting user engagement and retention. The depth of the implementation reflects a thoughtful approach to both user experience and code quality.
