Half way through i was like: "nah, this can't be true, this is a speeded up demo for sure". But then, i noticed that it really is the end of the game, the time makes sense, hum.. i don't know.
Right now, i'm a bit with carol: no keyboard could go that fast!
I guess this is that kind of thing: "see it to believe it". I'd believe it if i saw a real guy on a real computer next to me.
(even if it's speeded up, that guy plays tetris a lot better than i do
