7

7 is a single-player, 2-D, puzzle platformer.  Play as 0 and traverse the bizarre psyches of each number, in the hope of ending 9's tyrannical takeover.  In each mind, collect a +1 to increase your number, and with it, your number of jumps.  Use this simple concept of numerous jumps to complete increasingly complex challenges.

Control with WASD, and Space, or a gamepad.
