Welcome to "Feeling ReMorse"

Hi riddle players and welcome to my brand new riddle - Feeling ReMorse.
This is my first riddle after more than ten years, and second one regarding morse.
During the last ten years I continued to look everywhere for it,
and sometimes found it in the most unexpected places.
Some of those places are presented to you here.

This riddle assumes you already played the first one, and know your way around morse.
It is quite challenging, and there are no easy tutorial levels here,
so I advise you to play the first one if you haven't yet.

There are 20 levels in this riddle, not ordered by any level of difficulty,
each one presents a different idea, but all involve morse.

If you are willing to re-start the journey, go ahead and re-start
