Jump off the roof and hit the gravity switch as you pass it. This will allow you to run straight up the wall in front of you. Run away from the saw and at the top of the wall you will see a familiar sight. The neon H from the HOTEL sign earlier in the game, but this time it is on its side and as before, lights on means do not touch. When the neon light comes on, wait 1 second then jump off the top of the vertical platform and hit the gravity switch here to return things to normal. Jump across to the safe spot in the middle of the H. When it is safe to do so, run and jump off the right hand side of the H to a pipe below.
Turn back towards the sideways H and when it is safe jump down to the middle of the H then do a quick 180 and jump to the rope below. Drop down onto the O and continue to the right. You will enter a small room without a floor, but with a gravity panel close at hand.
Achievement/Trophy: Jump to the panel to reverse gravity and a crate will join you on the ceiling. Use it to jump back out to the entrance. Run outside and you will fall up to a secret spot on the roof. Run to the left wall and pull the handle here to reveal an egg. Stomp on it for the achievement/trophy - Going Up.
As you enter the room, jump to the gravity panel and as the crate comes up to the ceiling, jump over it and push it to the opposite side of the gravity panel. Return to the spot above the gravity panel and wait for it to expire. As gravity returns to normal, hit the switch one more time, then push the crate all the way to the right and use it jump up to another ledge above, jump to the right quickly to avoid the circular saw and slide down the slope to exit the room.
