Part 11

After obtaining the gear, throw it to the other brother across the ledge.

Cross the thin plank of wood, throwing the gear to the other brother.

Place the gear in the shaft in front of the lever and have both brothers grab a lever to ascend the inventor's platform.

Follow the inventor to his workplace and have Big Brother interact with him to get permission to use the hang glider.

Achievement: "Windpipe" - Behind the inventor's deck, find the stairs leading to a windpipe. Little Brother controls the side lever, and Big Brother grabs the bar below the windpipe. Interact with the levers to produce sound and earn the achievement.

Achievement: "Love Birds" (Part 2) - On the way to the hang glider, find a rusty telescope. Look through it and move your view southeast to find two birds on a branch, reuniting them to earn the achievement.

Interact with the hang glider with both brothers. Hold onto both interact buttons at all times during the flight.

To steer, reposition the brothers' weight on the glider. More weight on one side makes the glider veer in that direction.

Fly straight ahead past the cave; a flock of birds will damage the glider. Do not try to land on the pillar to the left; fly straight to trigger a cutscene.

After the glider crashes, the brothers tie themselves together with a rope to climb the tower.

Climb the vines. Have one brother jump to the metal handles.

To swing to the next handle: let one brother dangle while the other holds the metal handle. Keep the trigger down for the brother holding the handle.

Rotate the dangling brother's joystick to swing him side-to-side until he can grab the next metal handle. Release the previous handle and repeat.

Reach a wooden plank and swing across.

At the wooden ends jutting out of the wall, swing one brother to a higher wood end (not the horizontal one). Go up three wood ends, then swing left to another wood plank.

Sidle across the next wood plank until the camera pans, indicating you can't go further.

Swing Little Brother to the metal handle on the left, swinging through a crevice. Get as close to the handle as possible before swinging.

From the metal handle, swing over to the vines and climb up to level ground.

Walk to the bronze gate. Climb the gilded part and jump to the grabbable ledge.

Sidle to the right while still grabbing the ledge.
