Chronology is an intelligent platformer that plays on the notion of time. You have the before, and the after world. You must navigate between before, and after to complete progression through levels and develop the story. It is bright, it is colourful, and it is challenging enough to keep you thinking.
It introduces new mechanics on a regular basis, like changing time while you're flying through mid air in order to land a platform that was once whole, instead of a collapsed heap of rubble.
The voice acting is bright, and colourful, but at the end of the day.... my bias against platformers has to come out strong - jumping puzzles that involve you falling to your doom are never a lot of fun.
At least in Chronology, you don't need to start the level again, with some very forgiving restorative powers allowing you to literally spawn in the place where you left off. It is more about solving the puzzles - of which there are many.
Even though it is a platformer - it is one of the few that I would err on the side of "play this", as opposed to the abject horrors of things like Megaman which I was tormented by on my old Gameboy Classic. Check this one out of you want to educate children about time's relentless advance, and the fact that everything anyone will ever build will collapse and decay into a pile of nondescript junk. (Just like this article!)
It is a game about entropy.
