Idle Planet Extend

Idle Planet Extend is an idle space game where you run a team of astronauts and gather resources on different planets. You start on the Moon, then fly farther out to explore new parts of space and ship your haul back to Earth. Each planet has its own mission: build mining rigs, collect the required amount of resources, and load them onto the ship.

How to play?

On the Moon, first build an oil well. Pick up the oil that appears and carry it to the extraction point. To speed things up, call in more astronauts. Bring a few barrels of oil to the droplet icon to spawn a treadmill. An astronaut will start running on it, boosting production. You can place several of these helpers. Next to the ship, you always see a task that shows what type and amount of resources are needed for liftoff. Once you deliver everything on board, the ship immediately heads to the next planet.

The flow stays the same on other planets: gather resources, set up processing machines, and watch the greenhouse. Astronauts on the treadmills get tired and need food. Harvest crops and bring meals to everyone who is hungry. Move from planet to planet and stock up as much as you can on each one.
