This is the hardest part of the game by far. Use your bird form through out the stage,
because the walkways are narrow. To get past this stage you will need to do three
‘perfect’ long jumps. The first jump is the hardest.

In the first room, avoid the steam and go to the end of the room. On the back wall is a
4x4 ledge with a fan and a steam vent. You will jump off this ledge towards the left. You
will see a courage orb on the vent you are aiming for.

Note: there is a ‘yellow powder’ on the next vent shaft, but it is not worth the risk.

To perform this jump, stand at the edge of the ledge, now jump up and out, wait till you
are completely in the air, then at the very highest point press and hold the soar button.
You must be flying straight, so do not veer to the side hoping to save yourself if you
miss. It will look like you are going to miss, but don’t stop soaring forward, Lyra will
miraculously pull herself up. (from three feet away?)

This jump is hard to do because your reflexes (honed from hours of video games) will want
to hit the soar button too soon. The bad news is that there is no check-point near by, so
if you die in the next room you will have to do the first and second long jumps again.
Because of this, don’t bother trying the jump if you have less than three courage orbs,
just jump off the ledge a few times and start again with a full courage meter.
