Built using Microsoft’s XNA, it’s designed to only work with a gamepad of some nature, and ideally a 360 controller. The game is an attempt to create a reasonably accurate physics model of a human gymnast, albeit one built of rectangles, teaching you to spin, flip, grab and leap about the horizontal bars. It then gets extremely silly, flipping you from boingy poles down curved corridors of poles, challenging you to master the remarkably complicated controls. Left analogue stick does the top half of the body, right taking care of the legs. And there’s a slo-mo mode for mastering the trickiest moments.
