I'm not usually very good at analyzing things, but all I can say is the text does sound like it's alluding to depression. Along with few other things...
The environment is quite nice, but the game is a bit confusing - the only time the invisible wall goes away is when the character starts talking and I still don't know what triggers it.
The environment throughout the game play is quite calm, but contradicts the character's emotions. It takes me back to when I was young because I use to have depression or think I had that.
There are a few things I didn't like: how confusing the game is- as I mentioned above- and the length of the game.- it was quite short
Yeah, that's all.
