Day 32 and ¾. in which Seth explains this so-called "Autopilot" mode.
My mom just doesn't understand the concept of having my character auto-attack someone. It's not like my character will run up to every enemy he sees and attack it, as I still have to tell my character to attack it in the first place. And he'll only do physical attacks during this state of auto-attacking, nothing else. So it's alright to set my controller down while fighting bumblebees, but when I'm fighting more high-level creatures, such as Giant Enemy Birds, and I need to use special skills to kill them, just setting my controller down isn't going to cut it.
