Codex Game Face

Codex Game Face turns the official Codex pet into a focused local arcade. Pick Codex up in a Japanese apartment, boot GAME FACE, and play five original pixel minigames: Syntax Flux, Branch Predictor, Blink Buffer, Expression Cascade, and Compute Commons. Each game uses Codex’s expressions or face aperture as a mechanic, with accessible pointer and keyboard controls, reduced-motion support, deterministic systems, original sound, and a hidden persistent Orbital Compute secret unlocked by clearing distinct games.

Built during OpenAI Build Week with Codex and GPT-5.6. Codex accelerated product research, deterministic game-state and physics implementation, native pixel-art pipelines, accessibility, audio synthesis, automated tests, and repeated browser QA. The repository README and decision records document key design decisions, rejected iterations, and verification.
