Hmm, I like that you've given landfill its own texture, but I feel like it should gradually lose its grid shape with time. Maybe even grass over eventually?

I'm loving the game so far, but the music audio quality is bugging the hell out of me!
It has the sound of something that has either been compressed with a really low bitrate or been re-encoded multiple times.

Just bumping this because, apart from really liking Desura (and therefore liking the idea of seeing Factorio on Desura), I think it might help get some more sales since Desura sells alpha funded games.
