I absolutely haven't got the faintest idea what's going on here, yet I know that it is good. It's one of those occasions when I'd far rather be utterly mistified, than find out the reality of the situation, no matter how excellent it might be. Like watching Spanish soap operas, or The Bloomberg Channel.
(So no, I never played Tower of Goo, which you can get here.) [You really should play it, John, it's brilliant - Rest Of RPS Team.]
