Turnip Mountain

Just heard about this game and couldn't help but think how perfect this game would be for Nex. It is 2D platformer where you climb on walls and avoid obstacles along the way. You would climb by moving each hand separately, while holding or releasing your grip with the other hand. In the gameplay video, there are several great examples of different levels, obstacles, and techniques like launching yourself to jump to another location while not holding onto anything. Nex motions would be nearly identical to using two joysticks or two mice, but instead its your hands. Holding your position could be as easy as closing your hand into a closed fist so that you can move and reach with your other hand. Movements are only limited to the characters arms, but should be able to allow for some wiggle room so that you won't have to be exact all the time
