"Why set a limit for the amount of airbombs? "
I did it for balancing, because I thought that some players will just pick up that skill all the time and have an army of 10 air bombs, they can feel the game is too easy, but I was thinking about how make it without limit and maybe I will configure the "droprate" to decrease the more levels the player have in that particular skill.
Thank you for playing my game, I'm happy you liked the new character. I will consider the idea about the turrets.
