Lost in Blue: Iterating from an Idea toward a Playable Reality

The deck is organized mainly through dates, game footage stills, and prototype diagrams. All 44 pages preserve the evidence of design evolution. Video frames in the static pages remain stills; they do not indicate that the original videos have been restored.

All original presentation pages are included below. Text within images and video stills is unchanged. Titles and reading guides are translated into English; the full presentation text has not yet been translated.
