Design Game UI

Turn existing product content into a controller- or remote-first interface without losing the routes, state, actions, accessibility, or operational behavior that already make the app useful.

Treat game UI as an interaction architecture, not a visual reskin. Establish the action model, focus graph, layer stack, safe area, feedback, and test matrix before decorating the shell.

Route in-world 3D, world-space, and diegetic interface work to a 3D design workflow. Route gameplay movement, combat, camera, and vehicle control schemes to gameplay/input-system engineering unless the task also includes menus or HUD.
