When you get the last heart, shoot the Gol to the right, and get the chest.
On the right, push the left framer to block the medusa and get the heart. Shoot one Snakey and push it below the medusa, and grab the middle heart. Shoot the other snakey on the right, and push it below the other medusa. Get the heart on the left by pushing the right framer up two tiles.
