Click the preview button to view the game. Currently, there are 3 stars on screen. Click the Editor button and add two

Try the suggestion given by the challenge, and use the "preview" button to see the game image. The two added stars are just a little bit to close too each other and to one of the original stars.

Just change the coordinates to give them a bit more space so they won't overlap.
