Adding a trail and making net black is good idea. Ball shadow is more visible with black net. Hit boxes are fair knowing she will be a recruit with more buffs. Player hitbox starts near his knee and all the way up where the ball can go. I'm unsure because I have to add rest of the missing content and a ghost. Then ironing out a few bugs and it will be done.

You see her kick-off, you can choose to hit the ball to the rear left and hit the limit position on her right or take a ball from a distance as the author said, and then play a corner kick in close proximity. In addition, if you feel you are going to lose, you can run to her when she hits the ball and press "x" to clear the small score :)

can I ask where you found Gina?

I am convinced that as of now this mini game is impossible
