Developer Dimillian shares how good it is to work on his game "Duo" using Codex Mobile. Screenshots show a 20-minute remote session on his MacBook Air from an iPhone: adding PS1-style retro shooter details like rifle shots, shotgun spread, blood splashes, layered skeleton-break sound effects, and kill rhythms per weapon — with all 503 targeted tests passing and gameplay footage attached.
