Ladies and gentlemen of the BGS forums, I present to you http://www.foddy.net/GIRP.html, an absolutely diabolical little game that, unlike QWOP, is actually fun, not just funny. Basically you control a rock-climber trying to reach the top of a sheer cliff before the rising tide swallows him up. You move his hands one-at-a-time, reaching for hand-loops by pressing and holding the corresponding letter on your keyboard and pressing the "flex" button. Avoiding lifting the wrong finger and sending your climber plunging to his death is surprisingly difficult, although a musician will probably have an easier time of it.
My best height thus far is 20.2m.
