In order to explore the planet, you follow “Flow threads” that will fill your boots and gauntlets with Flow, the natural energy that powers pretty much everything in their world. It’s also used to get rid of the Rust, the red crust that corrupts the planet and creatures. Gather Flow, clean the Rust and discover resources: food or medicinal plants, materials for combat or to repair the Nest (your spaceship/home), or even souvenirs and items for your home.
