Has anyone else played this? It's only in the alpha of its build, but it's already very refined.... well, for a game with blocky graphics. Seriously, this game will play on my 6-year-old Dell Inspiron 8600 laptop with an FX 5200 64mb GPU. I don't know of any other current game that will do that.
If you haven't read up on it, you should. It looks like crap, but it is amazingly addictive.
