"Is it scrolls?" you might ask but no. This is a space game called 0x10c. Notch has this to say;
"Hi, I'm Notch, and this is my new game. It's going to be a space game, and it's quite ambitious!
The game is still extremely early in development, but like we did with Minecraft, we expect to release it early and let the players help me shape the game as it grows."
