Decent update. I'll have to play more to have a real opinion, but ti's looking good. Have you thought about releasing it as a downloadable? I'd love to play it offline, even if it's just a locally-hosted copy of the webpage.
Also, a minor bug, but it seems like the game is slightly too tall to fit on the page without zooming out.
Fuel's a bit too common in the early game now, though. Perhaps you could make it so that fuel occurrence increase somewhat as distance from spawn increases? Either way, making it both more common and more fuel-giving makes it a bit overkill. Just making fuel blocks mor would be common was enough; how much fuel fuel blocks give and starting fuel should be like it used to be.
