Fixed Some Game-Breaking Bugs

Fixed the following bugs since they were game-breaking and seriously damaging to the player experience for some players: 

• Some users have reported that the desktop section freezes up and becomes non-interactable. (Fixed!)

• Clicking on the Cave of Secrets while it is thanking you for giving it a secret results in it interrupting itself, which stops it from being able to give you the hidden letter. (Fixed!)

• MacOS users cannot use CTRL+Click to pan the camera. (Fixed!)
