Gravity Chamber Escape Wallboost (NSJ)

Allows the player to escape with the gravity chamber item using boost.
Note this requires you to NOT have gravity suit.
Approach the first cliff and wall boost off the corner rock, this is the easy boost.
From here walk to the large rock and perform a trickier wall boost off the rock and to the right, only need to angle a bit right to get the correct boost trajectory.
For the next jump use an underwater slope jump off the steepest part of the wall to gain enough height to reach the water's edge.
Last step is to jump out onto the ice.
