dari script ini tambahkan code agar saat meload file mid dapat memeriksa file mp3 dengan nama yang sama dengan file mid nya juga, dan ini optional, jika ada maka gunakan untuk di play untuk game, untuk bounce tetap menggunakan file mid, jika tidak ada maka gunakan saja sound dari file mid, buatkan dengan benar dan tepat : import pygame
