Star Defence is a unit placement real-time tower defense game.

Players can place their own units, "white stars," anywhere in 2D.
The "white star" will turn into a hostile unit, a "black star," over time.

The player's objective is to increase the number of "Black Stars" observed and to raise the "Civilization Level" of his planet.
Optimize the balance between "white stars" and "black stars" to be installed and observe "black stars" more efficiently.

Units will only operate when the number of black stars minus the number of white stars exceeds the civilization level.
To increase the civilization level, a certain cost is required, and reaching level 10 clears the stage.
