Travel the expansive solar system to find planets with varying resources, each planet is stronger than the last so you'll need to gather upgrades.Travel to the planets and gather as many resources as you can before fuel runs out, you can use these resources to increase your drills durability, fuel, damage and add quirky upgrades.The items you collect in the game have an automatic mastery system where the more you mine a resource the more buffs that resource will have, so if you mine 100 iron it will give you 5% more drop rate.
