you count from 0
if the amount of enemies is 1 , then the number is 0
if 2 , then the second one you choose 1 , not 2
0 and 1
so restart the game
when the battle starts, on the button, and off it when the slider is 0
when they are 2 , then after you chose 0 and on and off the button , you choose 1 and on then off the button , you will see it is working,
there are a lot of comments people passed more than level 70 , so have fun
