SWIFTMAGE'S PROFILE

I wanted to ask where the bonus dungeon is or how to access it. And also, what saving after beating the game even does. Reading through the comments I thought it was a new game+ thing, but when I load it up it just brings up the ending screen.

edit - lol! just answered my own question. I use a controller to play and pushing any of the buttons didn't do anything. So I hit some keys on the keyboard and I think Enter was what it took to move on.
