The story tells, that the character lands on a alien planet. Why is there a human-friendly atmosphere with oxygen?
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
What if you could build oxygen dispensers that slowly fill the atmosphere (you would need A LOT of oxygen to terraform the planet to breathable levels). Slowly increasing the oxygen level could reduce oxygen usage from inventory.
