For VR Vive owners I've added a new option that should show up in the pause menu labeled 'use arm jump' that when toggled on will allow jumping movements based on physical left+right arm movement(velocity and direction).
To trigger jumps using your arms, toggle the option on in the pause menu for the game modes 'Climb' or 'Crystal Hunt' (disabled in other game modes).
Now when you press one or both triggers, when one/both triggers are released, the sum of your left+right controller velocities are applied to your in-game player. The velocities applied are those at the trigger release - it doesn't track your controller movement or velocity while the trigger is pressed.
Still have to make a few additional fixes since the superjumps don't trigger using the arm jumps and also will probably add some sensitivity settings. Also in this mode I disable the grip rotation as I found myself unintentionally pressing the grip buttons when pressing the triggers.
Looking for feedback from Vive owners on how well the jumping(or flying in 'fly' game mode) works or suggested changes.
