The bug fix will be included in the next release :)
Unfortunately, a line of code was inserted in the wrong position. This caused the king to always respawn in the same (wrong) position.
First of all, rhx for reporting. But the respawn rate of the large balloon corresponds to the original, namely after every 9 small ones. Putting the king back on the right side is also intentional.
The game is based on the American version of the game. Maybe this version is different from the Japanese one.
