WallZ lays siege to the App Store

Brand new budget title, WallZ, has just been released onto the App Store (click 'Buy It!' below), and looks like quite an intriguing little puzzle game – even if the App Store description doesn't really give much about the gameplay away.

But judging by the screenshots your job is to detonate certain coloured squares to fell the castle wall and thwart the knights atop it. Merlin gets involved at some stages, too, while 'hidden elements' come into play to make your siege a bit more difficult.

Currently only boasting ten levels (still not bad for a game that's less than a quid to buy), developer Gamer Outfit promises regular updates to keep the action alive.
