Tiny thiefLeading mobile games developer Rovio has turned publisher, signing up 2D puzzle game Tiny Thief from Spanish developer 5 Ants.

Pocket Gamer reports that the game will be released in May, marking Rovio’s debut as a publisher.  There have, of course, been plenty of rumours about Rovio going down the publisher route in the past, with the company said to be talking to a wide range of developers at the end of 2012.

Given that Rovio reported 263m monthly active users in December, the move to publish third-party content should have developers rubbing their hands in glee at the prospect of tapping into such a massive potential audience.
