Update 1.6.1!

This update focuses on a few small features and bug fixes. Our last update took a very long time so we're adjusting things back the other way in an effort to get improvements out on a more frequent basis.

Features:

• Add screen shake; when you get hit by enemy fire.
  
• Add different shield effects based on which shield item you have equipped.
  

Bug fixes:

• Damage on items is shown to one decimal place to make upgrades less confusing.
  
• Create a upgrade limit for items that won't benefit from additional upgrades.
  
• Opening the inventory removes all item pickup popups.
  
• Fix boss enemy movement, will now fly at player instead of some random direction.
  
• Fix enemy movement; enemies won't fly at you backwards or oscillate left/right as they attack.
  
• Rework the mouse/controller turn sensitivity; mouse sensitivity has a wider range and mouse/controller have a better default setting.
