"You don’t kill the enemies in Ninja Pizza Girl. You can’t even knock them out. Sure, you can bowl them over for a second or two but if you hang around they’ll get right back up again. Running away is just as viable as attacking and sometimes more so. Running fast makes Gemma feel good about herself and feeling good is the most fragile resource in the game."

I'd say running fast isn't just about delivering pizza fast, it seems to be about avoiding bullies too.
