If you harbored even a fraction of the addiction I did for thr original Puzzle Quest, odds are that you played the hell of the flash demo that was recently released (and yes, I am quite aware it is only one level, I replayed it a ridiculous amount of times is the thing).
As if you weren’t distracted enough being able to play a round at anytime, this morning Big Download sent over the full PC demo this morning, which allows you to do a lot more than just fight the same battle over and over. The limitations are that you cannot pass level 5 or save your hero, but let’s face it, there sounds like there’s plenty enough there to make you ignore work for hours. Not that I advocate that, of course (do it NOW).
