It's an arcade game I originally created for the LudumDare game Jam. 

The theme was Your life is currency.

Meanwhile it has been further developed and improved. 

The Jam version can still be downloaded.

Gameplay

Shoot with your life and prevent the black hearts from touching the ground.

If you keep the Shoot button pressed, the shot charges and can hit more than one opponent.

But beware, every shot costs lives.
