My brother leant me this and it seems I'm addicted. "Just one more game, and then I have to go to bed/work/the toilet..." I. Just. Can't. Seem. To. Switch. It. Off. Seriously it's ruining my life.
For the record I can kick ass at 'Novice' level, but the step up to 'Professional' is tough and fiendishly frustrating. I want to beat the machine! Curse you, Nintendo, you've gone and done it again!
