I love Minecraft animation videos. This one is a very short one about the survival map “Skyblock”

Survival maps are user-created challenge maps in minecraft. They limit the starting available resources, so that you must use creativity and resource management skills to thrive in such maps. Eventually, you can improve your conditions by making use of renewable resources.

Skyblock is one such survival map: The map is completely empty, except for a very tiny sky island (shown in the video).
