The Life I Lost shouldn't be played by anyone under the age of 12, and deals with triggering topics. I classify them in two categories: those who are mentioned and those who are major.
It contains usual curses (nothing fancy or unusual) and non-sexual jokes about genitals (although sex is mentioned in the game).
Mentioned themes:
Absent father
Alcoholism
Suicide
Major topics:
Child rejection
Miscarriage
