So is she actually a government agent of some kind or is she just a corporate spy? Is the Japanese company she’s working for in our world or the game world? If the former, was Ray aware the whole time that she was a in a game? Why does the Japanese company need a puzzle dependency chart?
P.S. Hint tron doesn’t seem to work in final chapter of the game.
Everything’s open to interpretation, but my guess is: she is a government agent but also a corporate spy. The game company is a real world one, but Ray doesn’t know it’s a game. The company needs the dependency chart because it’s the best invention ever for point and click games.
