Click on the circle in the cube to select it, then use WASD or the Arrow Keys to move. Your goal is to push the box into the outlined spot. Right click on the mouse to turn the world to find the right path.

In later levels, you can move the larger cubes too! Click on a large cube to select it, and use WASD or the Arrow Keys to move it. Place cubes next to each other, then select the circle to move between them.
