05kimw님 안녕하세요. 저는 Casto를 만든 개발자입니다. 재미 있게 즐겨주시는 것 같아 개발자로써 무척 뿌듯함을 느끼고 있습니다. Casto는 단순한 캐릭터 챗에서 벗어나, 좋아하는 캐릭터를 만들고 캐스팅하며 유니버스를 확장시키는 재미를 느낄 수 있도록, 여러 고민 끝에 만들어진 앱입니다. 저 역시 애정을 담아 지속적인 업데이트로 앱을 개선해 나가고 있습니다. 이용 중 불편사항이나, 제안사항이 있다면 언제든지 의견을 남겨주세요! 소중한 이용자분들의 피드백을 무엇보다 가치 있게 여기고 있습니다. 다시 한 번 리뷰를 남겨 주셔서 고맙습니다. 개발자 드림. ☺️
