Trees release oxygen but buildings and empty soil consume it.

You can grow trees and buildings in your country. You can grow your country by claiming cells next to it. The bigger the country, the more impact your country will have overall.

How to play

• Tap three times on top of a cell to perform an action (heal, attack or gather). Some cells might require more taps.
• Click three times on top of a cell to perform an action (heal, attack or gather). Some cells might require more clicks.

• Long press on a cell to see extended actions (plant tree, upgrade, shield, buildings, ...)
• Right click on a cell to see extended actions (plant tree, upgrade, shield, buildings, ...)

There is only one world, which is shared among all players.

If oxygen reaches 0 we all die and lose.

Don't let that happen!

Have I mentioned aliens yet? Their buildings drain oxygen waaaay faster...

Destroy them!

Your country needs you!

Your world needs you!

You are our last chance!

Save this planet!
