I feel personally attacked right now.

Games have a tendency to mark one's objectives, which can be good or bad depending on what you want out of a game. These days with my schedule, I tend to appreciate them, but with time set aside, I can definitely see the appeal of having to figure out where to go rather than having it be clearly marked on your compass and/or map.

Like this one time, at Skyrim camp, I made it so there wasn't even a compass on screen, and I avoided using the map. I had to figure out where I was going via landmarks, and would even use the direction of my character's shadow to figure out which way to go. That's not at all something I'd want to do in the evening at the end of a long day, but at the time, and if I had a day free? There's something great about it.

As for Sarah and her transformation, I just wanted to draw it. Plus, Sarah just casually transforming herself with Tedd's wands for fun and to build up her own magic power muscles seems like a thing she would canonically do, up to and including that form.
