Letterpress: making me use Game Center since 2012

I don't know who's played it, but since its release yesterday it seems to have become so popular that Game Center is falling apart around it. It's a simple word game, but it's also insanely addictive. Someone pretty accurately described it as Draw Something without the drawing. If you haven't got it already, it's free with a £0.69/$0.99 upgrade that lets you play multiple simultaneous games (which you will do), and if anyone fancies a game, add me on Game Center - I'm Xavdog over there too.
