After finishing the score ranking level, if you start the score ranking level again without ending the game, it was discovered that the score was added to the previous score.
However, since there are players who have challenged the level multiple times and gained a high score, I would like to change this ranking to "How many enemies have been defeated" without modifying the game.
With "Air-Combat" and "SkyGameChanger-AirCombatII-", the score is properly reset to zero.
I'm sorry, but thank you for your understanding.
