The meaning of the word "missing" is portrayed frm the absences of stem of the letter "i". By leaving the titles, it portrays that a part of the letter has been removed, reinforcing the meaning of "missing".
There is consistent proximity throughout the logotype. The negative space forming the "N" makes sense with the name because looking at the logotype engages the audience when locating the "N". I also think the logotype font works well bold.
