• Removed some parts of enemies projectiles impact effects to reduce bright flash effects when they hit player
  
• Limited camera shake power for incoming damage
  
• Brightened up some places on level 2 and 5
  
• Fixed Wendigo sometimes stays in place for 1-2 seconds
  
• Fixed on level 2 if load save at the very bottom of pyramid portal didn't show up
