Rock Pocket Games

Everybody gets to be the big guy in this dynamic duo with a dissymmetry. Two codependent buddies use their accidental mass excess (and the cord it magically travels through) to bounce and rappel off of each other through treacherous levels where separation and a closing door mean instant death. Shiftlings features solo, local and online co-op puzzle-platforming over 5 planets, each comprised of 10 levels plus a bonus obstacle course. There's also a screen saver included, and a free demo is available. The one thing missing is a "puns off" switch for the in-game announcer.
