Miniature Against Bacteria

Move with A, X, B, P, each moves you to their corresponting diagonal direction.  Shooting is automatic. Press 8 to invert the control mode.

Your mission is to defeat all the evil bacteria (that's the plural of "bacterium") with your slightly unreliable shrank submarine. 80 of them.
Don't let your durability drop below zero.
