It's big, but like he said, the behavior needs to be tweaked. Navi won't be flying aroudn like she normally does. She'll probably only come out sometimes, so it's okay. If you watch some FSA videos, you'll see how it works. =D
Yeah, navi's awesome here, good job guys.
Oh, a little update of my own I guess?
I finished the top left corner of hyrule field and the gerudo entrance (xf, the screens are on pyxosoft), I'm probably gonna go for the actual castle entrance now.
