How to play:

Enemies will pop up from the center of the circle, use the mouse to aim and click to shoot them.

Enemies will follow you and shoot bullets,  When you are hit, the radius of the circle shrinks.

If the circle radius gets too small you lose.

Missing an enemy by shooting shrinks the circle.
