버전 별로 파일이 나눠진 것도 아니고, 지금 나오는 코드랑 최종코드가 너무 달라요 갑자기 잘 되다가 안되니깐 짜증이 몰려오네요 ㅋ

main.js에서 추가되는 부분만 따로 발췌했습니다. 저도 다시 보니 나중에 적용한 canvas 쪽 추가된 부분이 있어서 헷갈리셨을 것 같다는 생각이 들더라고요.
아래 내용으로 적용하시면 됩니다.
(해당 영상도 내용 반영해서 업데이트 했으니 필요하시면 확인해보세요~)

로직이 반복되는 내용이라서 시간 절약 상 복사해서 붙여넣을 수 있도록 한건데, 헷갈릴 수도 있겠네요~
해당 코드 부분만 따로 뽑아서 오늘 올려드릴테니 조금만 기다려주세요^^
