Добавление функционала в программу с turtle

При запуске кода и нажатии на копку паузы, черепашка рисует 3 кнопки, к которым привязаны функции и строку "PAUSES".

Помогите сделать так, чтобы при выполнении одной из функций, связанных с кнопками, кнопки стирались, и игра либо продолжалась без кнопок и строки "PAUSES", либо перезапустилась (тоже без кнопок и без строки "PAUSES"), либо завершилась и закрыла окно.
