Eunoia and Chaser Contrast
The Chaser has a mechanical nature, they are very limited and robotic, their movements are kind of stuttered, kind of unfree, like they can't escape their essence, they're silly and almost have no intelligence, they break easily by anything etc. They represent the embodiment of solely sticking to the known; repulsing and imprisoning from anything beyond the means of already charted territory. Eunoia, on the other hand, despite not participating much in the story, she always gives a feeling of universality, because she appears in several different places through the game, this in itself is already mysterious about her, but the fact that she is always available in different places shows a freedom and expansion that the Chaser doesn't have. Eunoia is almost as if it represented the acceptance of new ideas and the mapping of unexplored places of the psyche, the desire to investigate world issues and to be less ignorant.
