Save the leukemic Hermanator and kill off all the nasty LymphoBlasts swarming around in his blood. Beware of the friendly Leukocytes, killing them will cost you (and the Hermanator) some serious points.
And watch out for your own health. While navigating your HemoShip, don't bump into the Blasts, they will deplete your energy.
The game can only be played on a computer with a keyboard (hey, it's the Eighties again!) Arrow keys to control the HemoShip, Spacebar to shoot, P to pause.
Press H in start screen for help.
At the end of the game where you get the screen that shows your points, you can press <S> to save your high or (low-)score and send the Hermanator a message!
