One Step Back has all the telltale signs of pretentious indie gaming: a delicate, melancholy piano-led score; elusive interstitial text; gameplay mechanics as reflective metaphor for life. Yeah, it's just the sort of thing I love.
The icing on the cake is that it's also a good game.
In each level there are two doors, an entrance and an exit. Initially, the exit door cannot be used. As you move, however, it slowly fills with blue light until eventually you can run through it.
At the same time, the entrance door is bleeding white light until it spawns your past self, and then another and another and so on. These doppelgangers will each follow the exact path you took around the level and if you run into them at all, you die.
It starts to get tricky when you have to do several laps of a level before the exit door finally opens, all the while dodging half a dozen iterations of your past self. You'll easily catch yourself out if you forgot exactly what you did just moments earlier.
