Mining Madness

I don't know if any of you guys saw Minecraft. This little indie game made in java is slowly taking over the gaming world. The best thing is that it doesn have awesome graphics, or script. Whole world is made of 16x16 pixel blocks. You start with nothing, but in a short time you get, wood, coal, axe, sword, and even little carts. Of course there is day and night cycle, and some monsters like zombies, skeletons or crepers (they explode).

Minecraft  in alpha version got something like 1 mln users, and when it became beta version and the price grown it got even more users. I think that this is phenomenon in gaming world. All of game developers should ask Notch (creator of minecraft) about tips in developing.

So is there anyone playing Minecraft here?
