Khimera: Puzzle Island Version 2.3

Today we have some updates to the final boss, including a bugfix that I think was maybe introduced in one of the 2.X updates. Hopefully this resolves the issue:

Version 2.3 - December 20, 2022

• Fixed issue with no items medal not unlocking during the final boss.
  
• Final boss HP down from six hearts to five.
  
• Added additional five seconds to attack phase.
