The gemini gimmick? You must complete the constellation by filling the holes with the star bombs being thrown at you while jumping over the shockwaves, then if you succeed you silk to the twins statues to jump over the starfall waves. Remember to use silk midair so you will always make sure you'll teleport to a valid target.
There can also be an empty star spot hidden by the GUI at the bottom, keep that in mind.
