Oxyd

Oxyd is a 1990 puzzle game developed for the Atari ST and ported to the Amiga, Macintosh, MS-DOS, and the NeXT platform by Dongleware Verlags GmbH. It is a game of puzzles and tests to restart all the oxygen generators (called Oxyds) on the player's home planet. The Oxyds must be restarted by opening them in pairs of matching patterns, and (in colour versions) matching colours.

The Atari ST version was developed with the Megamax Modula-2 programming language.
