Post-jam update

This update adds some improvements and fixes for completeness.

• Controls
  • Optional pounce button separate from jump button.
  • Look up and down while standing still.
  • Controls help before entering the house (for Xbox controller).
• Gameplay
  • Doors and windows which require a certain amount of force to break.
  • Some objects are visibly broken when hit.
    
    • EDIT 11/29: Fixed broken object sprites failing to load.
  • Make bookshelves non-collidable. They provided safe havens from enemies, thus breaking the game (and not in a fun way).
  • Enemies search more aggressively after stumbling on a broken object, or being hit by one even if it doesn't knock them out.
  • Enemies push broken objects out of their way more easily.
  • Pouncing at the enemy from the front will also knock them out.
  • Fix collision problem when jumping up from under a table.
  • Endgame bonus for any enemies who never saw you. Enemy footstep volume and sight range are adjusted so that finishing with 0 witnesses is achievable.
• UI
  • Title and win screens.
