Hiya,
Thanks! Yeah, I have difficulty with balancing difficulty so things are reasonable to people who haven't spent weeks staring at the game.
As far the controls - if you tap Left on the dPad on the title screen until the symbol in the bottom-left of the screen is an "A", it should switch things so that crank and turntable rotation matches. I personally find that a little too twitchy, but the option is there (and I really need to tweak the UI to make that more obvious!)
