To make the stickman run, use the WASD/arrows or click the mouse and pull in the right direction. From a mobile device - screen joystick. Collect bricks of your color and grow. Green gates and balloons increase height, red ones decrease, yellow ones double. The number above the stickman's head is his height. If your height is greater than the height of another stickman, then you can run up to him to break. You win when your stickman is alone in the arena.
