Oxyd

Oxyd is a computer puzzle game released for the Amiga, Atari ST, Macintosh, PC, and the NeXT platform by Dongleware Verlags GmbH in 1990.
It is a game of puzzles and tests that challenge the player to restart all the oxygen generators (called Oxyds) on his/her home planet. The Oxyds must be restarted by "opening" them in pairs of matching patterns, and (in colour versions) matching colours.
