BBC Worldwide has released its first Android app: a port of iOS game Doctor Who: The Mazes of Time.
Originally developed by Scottish firm Tag Games, the game sees the Doctor and companion Amy Pond battling Cybermen, Daleks and Silurians. It came out on iPhone and iPad in December 2010.
On Android, the game is using in-app purchases as its business model. It comes with a set of free levels, with other packs available to buy within the game.
