This is one amazing AVN. You will be hooked before Episode 1 ends, and then you can binge on 18 more episodes, as ILSProductions releases this Episode 19. You will enjoy the stunning graphics, and the music and the sound effects. The story goes back and forth (hence the game's title) from a very pleasant past, to a bleak current time, where a worldwide pandemic has decimated the population. But this is a hopeful, uplifting story. I love the pacing, which rewards and terrifies at times. I rate this game five stars too.
