You are a magical smiley shape, and you have learned how to shrink things. You must now use this power to make your way to the glowing grey square of a GOAL. You must complete each level by shrinking the right things to make you end up in the right place. Use the mouse to click on the shapes to shrink them. As you shrink things you gain mass, that mass can then be used to give things mass. You add mass by holding space and clicking. Use the shrink and mass clicks to move your smiley to the end goal of each level as fast as possible.
