Online multiplayer for mixed-ability players — visually impaired and sighted together in the same game loop — is an unsolved design and engineering problem. The mechanics, the lobby system, and the audio-spatial interaction layer all had to work as a coherent whole, not as an accessibility bolt-on. Doing it in Unity, on mobile, with a functioning prototype as the deliverable, inside an EU-funded research timeline.

Contributed to architecture and feature development across the full stack: multiplayer lobby in Unity, experimental game design built around spatial audio as a first-class interaction primitive rather than an afterthought, and asymmetric player roles that made visual impairment a design variable rather than an edge case. Shipped a live prototype as part of the XR4ED Horizon Europe programme — one of 20 selected projects from an EU-wide open call, demoed at conferences in 2025.
