Child Of Light is halfway between a fairytale poem, inquisitive platformer and turn-based JRPG; and is absolutely shaping up to be a game to be reckoned with. Though a digital download, many retailers are selling a deluxe edition, which contains a download code alongside some merch. Amazon's £15.99 price is unlikely to be much more expensive than the base game, making this a bit of a steal. Thanks to Jas10 @ HUKD!
I'm reliably informed that the PS3 and PS4 version is playable across either or both platforms.
