Out of Oxygen is a platformer game where the player must make sure he have something to breathe.
 

You are a scientist who has crash landed on an unknown planet without breathable atmosphere. You will have to explore the surroundings to find the four missing parts of your ship to leave. 
For this, you will use oxygen relays which not only allow you to breathe but also to appropriate the terrain. If you have none left, look for sparkling green crystals: Sylvanite. With those crystals you can have new relays and advance further. 

Survival advice: Don't stray too far away from the oxygen bubbles because in this peaceful world, your only enemy is asphyxiation.
