Pah is a side scrolling space shooter with a difference, rather than using traditional touch screen controls the game is entirely voice controlled. To move the ship upwards you say 'ahh' and to shoot you say 'pah'. There's a number of levels to work through, with the usual aim of avoiding obstacles and shooting enemies.

The game play is relatively simple, but the novelty value of voice control is rather fun. It's no suprise, therefore, that Pah has been downloaded more than a million times on other platforms (Android and iOS).

Here's a video, published by Nokia, in which Yosi Taguri, CEO of Lagboo, gives a demo of Pah and explains some of the game's background.

Pah, which costs £1.49 / €1.99 / $1.99 can be downloaded from the Windows Phone Marketplace.
