-## 현재 확인된 문제
-
-가장 먼저 확인해야 할 문제는 배경입니다.
-
-의도한 방향은 기존 공항 사진 느낌의 `Sky.png`를 바탕으로, 반복이 덜 보이도록 긴 배경 이미지 `Assets/Sprites/Backgrounds/Sky_AirportLong.png`를 사용하는 것입니다.
-
-디스크의 `Assets/Sence/Main.unity`에는 다음 설정이 들어가 있습니다.
-
-- `Background/Sky`와 `Background/Sky (1)`가 긴 배경 스프라이트를 참조
-- 배경 한 장의 크기: `81.92 x 10.24`
-- 두 번째 배경 위치: `x = 81.92`
-- 두 배경을 루프시키기 위해 `BackgroundLoop` 사용
-
-하지만 Unity 에디터에서 열려 있는 씬 메모리가 외부에서 수정한 씬 파일을 즉시 다시 읽지 않아, 실제 플레이 화면에서는 배경이 제대로 보이지 않는 문제가 확인되었습니다.
-
-다음 스레드에서 먼저 할 일:
-
-1. Unity에서 `Main` 씬을 다시 열어 디스크의 씬 변경 사항을 에디터에 반영한다.
-2. `Background/Sky`, `Background/Sky (1)`의 Sprite가 `Sky_AirportLong`인지 확인한다.
-3. 두 오브젝트의 BoxCollider2D 크기가 `81.92 x 10.24`인지 확인한다.
