Move left, attracting the attention of both guided drones, and hit the switch. Then, jump up, and travel to the left side to hit the switch there. Fall down a bit, then jump into the middle area using the bottom-left entrance. Get the gold on the left side (optional), and then move right, using the bounce block to move into the terminal spot (as both doors were opened). Hurrily exit the area from the top right exit, and make your way to the door.
