Aye I’ve beaten her. At the end her stomps keep coming out of nowhere, sprinting does nothing.
She will try to predict where you trying to run, try to confuse her going in one direction and change to else when the stomp came :3c
Ah! When her anger meter is 100%, if you wiggle LEFT and RIGHT arrow keys, she's easier to avoid, if you listen for the sound cues of when she's going to stomp again.
