About Star Defence
Star Defence is a real-time tower defense game where you place units across a 2D space. You manage white stars and black stars to increase the number of black stars you observe and raise your planet’s Civilization Level.
Manage the stars
White stars turn into hostile black stars over time. Units operate only when the number of black stars minus the number of white stars exceeds the Civilization Level, so you balance their placement to observe black stars more efficiently.
Raise civilization
Raising the Civilization Level costs resources. Reach level 10 to clear the stage.
