This is great!
I like the way this doesn't poke fun directly at Minecraft, only the fickle nature of some players. The graphics are simple, and the voice acting is top notch.
I love the lip sync in this - it's done perfectly.
I also laughed at the gooey seriousness joke. I was expecting some more Minecraft related jokes, and perhaps something longer, but what the heck, it doesn't matter.
Well done, this is very enjoyable.
