Lonely Tower

To go further you’ll need to extend the pink bridge as shown in the picture.

The bridge moves back-and-forth between this room and the room to the right (Page 11).  Go back into that room and shoot the switch opposite the door to move the bridge.  (It’s best not to be standing on the bridge when you do that because it’s a long way down.)

When the bridge is in place, go through the door on the left.
