Haha I lol at the spinning part. I remember being a noob spinning around in circles whilst shaking the nunchuk frantically. You can always tell a noob when you get close, its always the same spinning and shooting and bashing. Lets call it the noob dance lol.
Well the obvious reason this happens is by overreacting and pointing your wiimote off screen. Therefore the only way to not have this happen is to not over react... It takes a bit of experience and practice but if you're still doing the noob dance after level 20 Id say its time to give it up.
Also, there is suppose to be a setting to turn of the keep scrolling whilst wiimote is off screen. I tried it once but it totally messed up my play.
Great story and keep it up Very entertaining!
