dari script ini tambahkan agar square nya ada efek glow yang menyinari map, dan bounce peg yang tinggalikan juga bersinar, jadi map nya sebelum di lewati gunakan efek agak gelap, jadi saat square datang membawa cahaya dan bounce peg yang tinggalikan juga memiliki cahaya glow, buatkan dengan tepat dan benar : import pygame
