I third the request for using the keyboard to move my characters around, and second the request for a map of Lynaeus to be easily accessible. Perhaps put it in the codex early on? I haven't played for very long, so forgive me if it's already there.
Also, it would be super neat if you could click and hold the mouse to move your character. e.g., if you click and hold the mouse down to the right of center your character would keep moving to the right as long as there aren't any obstacles in the way. You might not want this enabled in combat mode. I don't think it would be terribly hard to program.
Great game so far Jeff!
