Just from the screenshots, Chronology seems to be a game that doesn't really fit the Steam audience. Might be better on Facebook, Humble Bundle, or a tablet device.
I don't know, braid/limbo/etc are all successful on steam and it looks like a platformer that could be considered vaguely similar?
I never saw it on the steam sale, and unless it was accompanied by some good press I'd not have clicked anyway. I still have 10+ completely unplayed sale games to get through...
