Click the character to place a Tsum Tsum. To change your character, press space bar, there are 7 to choose from. Press t to change backdrop. Press c to clear the screen. Use up and down arrows to change the size from small to medium to large, and left and right to rotate it. I prefer down and up to stack.
Thanks to Disney Tsum Tsum wiki Now with Han Solo, Chewbacca, Jedi Luke, K-2SO, and a Death Trooper!
