Shrink It is a super fun concept in physics games. Use your mouse to select the object you want to shrink. As you shrink objects, you'll see your "mass" meter in the lower right hand corenr grow. You can use your mass in certain levels to make objects expand. Your goal is to get the blue smiley into the light blue box with rounded edges. You'll have lots of ways to get your goal in every level, like shrinking certain shapes to create ramps or using other round and rolling objects to push you into your goal box. Every level has you scratching your head and finding new ways to create and innovate so give Shrink It a try!
