It's hard to be 2D in a 3D world, which you'll soon find out if you play this austere little platformer from Henning Steinbock. But don't let the minimalist atmosphere lull you into a false sense of security, because you'll need to do all your best wrist exercises from that mandatory carpal tunnel workshop your boss made you attend last spring if you're going to be limber enough to keep this line on track to ultimate victory. Jumping Line is a great example of a simple idea done well that will appeal to all the oldschool gamers out there who don't need a lot of bells and whistles to have a good time and break a satisfying gamer sweat.
