In my frustration with Piston Hondo, I decided to try something totally different when I played Punch Out! last night. I had been using the Wii Balance Board to dodge left, right and duck. I decided to abandon this last night and just use the nunchuck's thumb control.
My decision was rewarded! I got through Piston, Bear Hugger, and Don Flamenco!
I am now on Aran Ryan. He is tough one, and many have issues with him. You have to be precise in your timing in order to get in multiple punches, but this goal will be much easier to reach now that the Balance Board sits unused.
