Kopf der Figur behält beim Laufen seinen Umriss

In zwei der vier Laufbilder hob sich der Körper um ein Pixel, und der
dunkle Umriss oben am Kopf fiel aus dem Bild. Laufende Figuren
flackerten dadurch am Kopf. Jetzt sinkt der Körper, solange die Beine
gespreizt sind, und über dem Kopf bleibt immer eine Zeile frei.
