I actually liked the way this topic was included in the story. It's very realistic because the character you play isn't depressed or suicidal herself, only her roommate. In this situation you can't know exactly what goes on in someone else's mind/life. People you see everyday could be suffering but you have no idea, you live your life. Depression is silent and that's why it's deadly. I think this game handled this theme very well and it's a very difficult thing to do.
Only 2 minutes into the game and I was close to tears because it spoke to me in a way no other game or any other media did before.
But more importantly, you didn't enjoy the game and that's fine, but it doesn't mean it 's a bad game. It just didn't work for you.
