This was a slightly bigger one, so here goes:

• New swords! You can now use a flame sword, a chainsaw, or a pixel sword (my personal favorite) instead of the default lightning swords.
  
• Achievements added, though not all of them are guaranteed to work as intended
  
• Bigger elevator buttons
  
• Music gets much quieter when there are other sounds (I hope this removes the need for a mute button, though we'll see).
  
• Several minor bug fixes and graphics tweaks that were never written down anywhere
  

As always, please let me know if you have any suggestions. That's how these games get better.
