Jones just ruined my Saturday by introducing me to Zwok. OMG. It's a flash game, from Sony Computer Entertainment Europe (who are presumably supposed to be making PS3 games or something. Maybe this is them 'goofing off'.) and it's BRILLIANT.
First, the art is superb. Really, top of the pile stuff. Secondly, it's easy to grok. Thirdly, it's ruthless.
.. and cute, and funny too. It's tactical snowballing without ever leaving the house. Which is now what I'm about to do, all day.
