Sony's released Knack’s Quest on iOS, a Bejewelled style title, which allows gamers to collect parts in order to make Knack grow stronger.
Unfortunately I have an Xperia Z (yes Sony it's you're phone) and as far as I can see the game is yet to materialise on Android and therefore I can't really give you impressions.
If you have an iPhone you can download Knack's Quest here. If like me you actually have an Android phone, then for now you'll have to wait.
If you do manage to download this title why not leave your impressions below?
