Game developer easter egg
When inside Linda's head, go to the end part where the skyscrapers are. Go to the last one on the far left and climb up it until your right above the fifth row of windows. Force the camera to the right until the mountain is in the way. There is a picture of a girl there. The girl is the girlfriend of one of the games developers.
Secret Message
After achieving the highest rank possible (i.e. after getting EVERYTHING), in The Collective Unconscious, there'll now be a line of text flying around saying, "All levels 100% completed, congratulations Psychomaster!"
