To solve the puzzle, use the camera to observe which tile on the rotating platform intersects with the pendulum when it meets the wall. If you observe correctly, you'll see that the tile with the square on it intersects with the pendulum perfectly on the left side of the room.

Grab onto the pendulum as it swings across the tile next to you.

Now, don't jump on the square tile or the blade will crush you. Instead, jump on the tile just behind the square tile (counterclockwise from the square tile). That way, you'll miss getting sliced by the blade, but you'll be only one tile away, letting you jump to the blade and grab hold.

Use the camera and position it facing Gabriel as he stands in the doorway. When the square tile comes in front of Gabriel, leap to the tile just behind it. Stand on the tile and glide to where the pendulum meets the wall. When the pendulum intersects with the square tile, place your mouse cursor on the pendulum and notice the hand-grabbing icon. Press the mouse button, and Gabe will grab onto the pendulum.

Save your game here. Your next task is to leap onto the platform in the center of the room, and it's not easy, considering the fast swaying motion of the pendulum. Take a few moments to observe the motion of the pendulum. Remember that the force of the motion will cause you to leap off in the direction if its movement. In other words, don't attempt to fall straight down off the pendulum. Wait until you're about halfway from the side wall to the platform in the middle, then place your mouse cursor over the platform (and observe the hand-grabbing icon) and click your mouse to leap to the platform. Again, it's wise to save your game here in case you miss. If you miss, just load your saved game and try the leap again.
