Aether is a video game designed by Edmund McMillen and Tyler Glaiel and published by Armor Games. Released on September 3, 2008, it can be played for free online or downloaded for offline play. 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.
McMillen and Glaiel created the game and developed it in 14 days. Both developers expressed interest in seeing a version being released on the Wii game console through the WiiWare online service. Aether received a positive response from video game blogs for its unusual visual style and atmosphere. The single looped piece of background music received a mixed response and the controls were highlighted as an area of the game that could have been improved before release.
