At this game jam, you'll be able to create a Fan-Made Minecraft Update of your very own. I guess you could call it like a Minecraft mod-making jam. Here are the rules you have to follow:

• Must be appropriate. Any inappropriate games will be taken down.
• Must add at least 5 new mobs
• Must add at least 8 new blocks.
• Must add at least 3 new items
• Must add at least 2 new dimensions.
• Feel free to add in anything else that you want in your update.
