Not much to say here, just made a decision this morning and implemented it!

• Added a button for toggling inverted climbing controls in the settings -- they're inverted by default but can be changed to suit preference now.
  
• Added a prompt in the tutorial regarding inverted controls, so the option doesn't go unnoticed.
  

Inverted controls are still recommended, because they allow for overall smoother/faster movement, but I decided I'd let people decide what's comfortable. Hope this helps!
