Talk to the NPCs (press UP near them), defeat the battles, and eventually you'll have the chance to face the Wizard. But you can't proceed after that, as there's no more content. You do get a 4th extra battle though.
Alexin, would the little stop when landing be the source of the problem, or the general feel of the motion? I redesigned part of the battles, and didn't reevaluated the main character motion when doing so.
