What's Oxyd® ?

Inside your computer there is a secret world of slumbering bits and bytes, of which you may not have known until now. But now this world is threatened and desperately needs your help!
 
Overnight the life-giving Oxyds have shut tight. Unaware of the danger, the world threatens to suffocate. Only you can rescue this world by opening all of the Oxyds.
 
Every landscape in this world has a certain number of Oxyds, which you must find and open with your black marble. But watch out! Oxyds will only stay open and release their oxygen if they are of the same pattern or color and are opened in order.
 
Not until all Oxyds are open can you proceed to the next landscape. The various objects lying about can be collected by rolling over them.
 
However, you can avoid picking up an object by holding down the mouse button when approaching it. Once collected, an object appears in the lower part of the screen and can be sorted by moving it with the right-hand mouse button. A maximum of 13 objects can be collected.
 
The object placed at the lower left of the screen can be activated or put back in the landscape by using the left-hand mouse button.
