It's a piece of art. The way it was written, not too descriptive but not too bland, the way it gives you good choices but also gives you hard choices too, and the little bits of comedy through it.
My character in my first run was a male plumber that plays video games. I managed to save 2 people (saying who would be spoilers), I didn't die once and I got one of the best endings.
I love this game.
