Update 1.02

I've mostly been working on stability, but some gameplay tweaks too. Unfortunately there are still a number of ongoing crashes out there.

Major Fixes

• Fixed crash when changing weapons quickly after deflecting an arrow
  
• Checkpoint files are backed up before saving or starting a NG+, to prevent lost progress in the case of corrupted save files
  
• Fixed crash changing graphics setting
  
• Fixed crash in UI
  

Performance

• Full res torch shadows disabled
  

Gameplay

• If you accidentally damage Anna too much, she will forgive you after killing you once
  
• Halberd does more damage to compensate for its higher requirements
  
• Reduced swamp slow
  
• Late game castle enemies made a bit easier, bosses a bit harder
  
• Fixed Zarristar exploit with greatsword
  
• Fixed Fuel Jar exploit
  
• Fixed Fire Blade Oil effect not showing up after an exit
