Let me know when there is a game to be shown off. This is a java tech demo that takes place in one room. Listening to him rattle off features he "plans" to add does nothing for me, after seeing all of the abandoned ideas in Minecraft.
People all over the net keep saying "yeah it looks like crap but the game looks interesting": What game? Having a 16-Bit CPU emulator in a room with N64 textures, and stencil buffered lighting isn't even close to being a game.
