I'm still not sure what you want to hear from me, it's a videogame for entertainment purpose. If you are entertained, that's the point.
i think they mean like what's the dev trying to tell us. like Undertale is about the importance of choice, and the game sally face is very much a game about humanity and how people react to tragedy. sometimes these things are up for interpretation and sometimes they are very clear like the game that dragon cancer and about the battles of having a loved one go through cancer. the commenter is asking what the message was.
