Click on the other button with the scratch cat on it. Then it will change to Gobo or Nano. Nano if you click it two times. And that's it. you can just move around with the character you picked. Unless you clicked start. ¯\_( ͡° ͜ʖ ͡°)_/¯
Just a simple test made by myself. :) Also If you pressed start already you can press space to change your character again.
