If you've played QWOP , which is now available on iPhone, then you know the limits of madness. I'm not sure if the Dr. Bennett Foddy's latest game, GIRP , is technically harder, but it will have your hands stretched across the keyboard like a game of Twister.

All you have to do is press the corresponding key to tell the man which handhold to reach for, and flex his muscles or use momentum to swing in that direction. Keep climbing and don't let the water catch up. Simple, right?

They should really give this to kids to teach typing skills. We'll have the most psychotic grade-schoolers ever.
