Markus "Notch" Persson is mainly known as the man behind Minecraft, but he's quickly developing a reputation for eccentric games that cover everything from speed typing to existential drama. If there's any doubt, you just have to look at his latest title, Cliffhorse. Yes, it's as absurd as the title suggests -- you play a horse pushing a giant ball around cliffs, and there isn't more to it than that. However, that barely-there design (which took all of two hours to build) is really the point. Persson describes the Windows-only game as a jab at developers who abuse early access programs by charging money for "minimum effort" releases, where most of the content theoretically comes later. And yes, he's aware of the irony given that he charged for Minecraft well before it was finished.
