Changes:

• Added space snowman! Catch him and get 3 carrots! It will appear during 15 days before and after the new year. It can also be found any other time, though rarely.
  
• Added hidden (and probably a little obvious) achievement.
  
• Added electro field sound.
  

Improvements:

• Reduced damage flash.
  
• Selected buttons made brighter.
  
• Reworked ship control - may feel some different, but mouse now works better.
