After that it was pretty much plain sailing until the 100g 'cheevo popped up for finishing the game.
That, if I'm not mistaken, bring my total to the year to 36 games which I'm pretty proud of. Yes there's been a few Easy ones. But not enough games let you change the difficulty mid game. It's difficult to know what kind of challenge lies ahead at the option screen.
