Very solid gameplay. too much fun :) I agree with klrorca, though. At ~30 min until you've bought everything, though, it feels like more of a demo than a full game.
I think a "full" version of this game could make a big splash on steam/xbox live/PS network. We can only hope they do so either with this or a sequel.
P.S. I would *love* to see the source released. This game has tons of modding potential :)
