You play as a tiny sentient planet. Maintain your ecosystem, create new plant species and discover the hidden powers inside you. You’ll need them soon, because there is a human spaceship approaching with the intention to mine all your resources and they don’t care if it kills you in the process.
Looks like there’s also an android version https://play.google.com/store/apps/details?id=com.TeTerka.Planetka
