Idea: add goal horns
You know how when you score, you hear that satisfying goal horn, well what if they were customizable. For example you could make 2 new sections in the bridge locker. One would be for the goal horn you hear, while the other one could be what your opponent hears. When the other team scores you hear the horn of their choice. You can have the choice to set the same horn that you hear as the opponent hears when you score. This adds lots of personality to the way the game is played and the community could request certain goal horns in future updates.
