Aether is a video game designed by Edmund McMillen and Tyler Glaiel and published by Armor Games, released on September 3, 2008. Players control a lonely boy and an octopus-like monster that the boy encounters, solving puzzles on different planets to restore them from monochrome to color. The pair travel through space by swinging on clouds and asteroids with the monster's elongated tongue, searching other planets for life to which the boy can relate. It is also a part of The Basement Collection.
