Data-Fidelity offers a single-player, five-stage walking game called Binary Boy that reminds me a bit of a stripped-down ibb and obb. You move left and right while flipping between both sides of the center of gravity.
I enjoyed how I fought enemies with just flipping. I really think the game opened up at the end, when everything began to go askew.
To say more would spoil the 15 minutes of fun waiting for you, so hop over to this link to play Binary Boy online or grab the Windows standalone build… or watch the somewhat revealing gameplay trailer after the jump.
