v. 0.9.5

Hello. Here I am, mostly fixing bugs again.

General

• Arranged the power-ups page to list 10 power-ups at the time and show the currently listed under the scrollbar
  

Bugs

• Possible crash on startup due to new power-ups save system (bool argument is unset)
  
• Old enemies did not get properly destroyed in mountain and volcano maps resulting in late-game lag
  
• Chickens did not prioritize important enemy targets properly
  
• Player could die with some health if "health on kill" weapon bonus triggered after death
  
• Fire Cape and Cross fire effect did not animate
