The players move to hit the fireball, if the fireball (f) moves past a player, there are border sprites l and j that should be increasing the score when the fireball touches them. What is happening
When the fireball touches the border the score will not increase. If you push the fireball into the border it will increase the score, but it will not increase it when it touches the hitbox.
There may have been some updates since your last message, but I only see line 88 where the score is programmed to change and it does change when you push the fireball past the border … If you still need someone to look at it, let us know.
