Press the green flag twice :-) > Use your mouse to guide the white blood cell left and right. > Deflect the germ with the white blood cell. > Don't let the germ past! * You can press space to track the variables.
This is an adaptation of the "Germ Fighter" app made through PLTW on MIT App Inventor. -> There are a few bugs I might not know of, but there is one where the germ freezes while on the defender sprite. Just move the defender sprite away from it and hope it deflects. Made in ~4 days on and off.
