리눅스 기반 테트리스 급질문입니다. 부디 답변 부탁드립니다.

안녕하세요,
제가 우분투 상에서 테트리스 코드를 짜봤습니다.
기본적인 기능들은 잘 동작하는데 일정 시간이 지나면 블록이 내려가는 기능이 동작을 안하네요.
강제로 내려보내면 잘 내려가는데 혼자선 절대 안내려가요.
일단 증상을 말씀드리면 아무 버튼이나 막 누르고 있으면 한칸씩 내려가는게 보입니다. 그러나 가만히 놔두면 화면상 블록은 내려가질 않네요. 그렇게 잠시 두다가 뭔가 누르면 순간이동하듯이 저 밑에 내려가 있는걸로 봐선 한칸씩 내려가는 기능이 돌아가고 있긴
한건데 이게 출력으로 나타나질 않습니다. 이문제 해결하려고 시간에 맞춰 내려가는 부분만 따로 스레드로 빼서 돌렸는데 역시 안되네요. 코드 첨부합니다. 제발 아시는 분 답변 부탁드려요. 너무 답답합니다.
