Minecraft creator "Notch" joined this thing called the 48-hour game development challenge which had developers make their own game from scratch in a span of 2 days. Markus "Notch" Persson made a top-down Zelda looking game which had some crafting elements similar to Minecraft.
Originally this game was named "Minicraft" but Notch has then since tweeted that the game is now going to be called "MiniTale" and even snagged both a .com and .net domain for it. He also announced that there will be a sequel to this game so MiniTale may get a full release some time soon.
You can try out the game for free here.
