A vertical scrolling shoot 'em up where you play as a ship made up of a collection of organs. The player's ship fires in time with it's heart beat. Whenever your ship grazes(comes close to but not hitting) an enemy bullet, it increases your ship's heart rate causing your firing rate to increase. If you are hit by an enemy bullet, your heart rate decreases and your firing rate with it. If your heart rate drops to zero, you die.
