In Star-Twine, you play as a small point of light traveling along a sprawling three-dimensional map. As you fly around the level, there are different kinds of structures you can build. The game emphasizes positioning and timing rather than micro-management, and there are many options open to you at all times. Your objective is to destroy the enemy's structures before they destroy yours.
Energy nodes extract energy from the threads that make up the world. Energy is used to build all of the structures in the game.
Turrets shoot at the closest enemy structure. With enough of these, you can take down any target.
Black Holes are a defensive structure. They have a gravitational pull and absorb incoming turret fire.
Defenders are used to stake out territory. They destroy any enemy structures that are nearby.
Missile Launchers charge up and launch themselves at the enemy, destroying multiple structures on impact.
