Ah yes, two updates in a day. Dying trying to balance the final boss.

General fix & adjustment:

• Fixed the invisible cursor sometimes hovering over the enemies during selection making it look like you're stuck selecting one enemy
• Reduced The Keeper's max HP a bit

Final boss fixes & adjustments:

• Fixed the minions becoming immortal after being revived
• Fixed some of the sprites moving off-screen after being defeated
• Fixed the boss' guard halving the damage taken from a minion's defeat
  
• Adjusted the minions' stats based on their moves for balancing purpose
• Made the minions less mean
  

The final boss should be easier to beat now.

If you'd like to play the updated version but would like to continue your progress from the previous version you can do the following:

Open the previous version's game folder -> www -> copy/move the "save" folder to the new version's "www" folder

Have a good day!
