I may not really grasp the entire message that the film wants to convey but  this short was nevertheless a joy to watch. The "gorilla" idea may or may not connote symbolisms during the entirety of the flick other than that it was represented by a mask worn by the mysterious woman.  The question as to when the universe will end was somehow answered towards the end when a woman's voice says "it's endless" while the scene shows a sky bedecked with countless stars, a sight to behold.  There was tension when the woman came into the picture, yes, but there was also a realization and a  sense of celebration towards the end. Do check out this short film.
