This thesis presents the design, implementation, and empirical evaluation of "Cosmic Sonar", an experimental web arcade game inspired by Space Invaders developed using native web technologies (HTML5, JavaScript, Web Audio API). Moving away from traditional retrofitting practices, the project embraces universal design by combining real-time procedural sound spatialization (stereo panning and pitch modulation) with native keyboard interaction and screen reader compatibility adhering to WCAG and WAI-ARIA guidelines. Empirical evaluation through in-game telemetry and SUS/AUS usability scales demonstrated that the audio-first gameplay creates a fully inclusive, balanced, and competitive experience even under total visual deprivation (Hard Mode).
