Engadget is reporting that the Finnish game maker Rovio has launched Bad Piggies, a sequel to its smash mobile game series Angry Birds. Bad Piggies is a physics-based title like its predecessor, but it offers a very different goal — instead of chucking items at structures to destroy them, it requires gamers to move a pig around the screen.

Rovio hopes to become the first pure-play mobile game developer to create multiple hits for the smaller screen. While plenty of other developers and publishers have made a lot of money in mobile gaming, most of them — EA, for instance — have viewed mobile as an extension of console or PC gaming rather than its own platform.

Rovio obviously understands the mobile medium, and Bad Piggies will surely get a boost from the placement and exposure only big-name developers can enjoy. But Rovio’s brand still isn’t very well known among most consumers, so Bad Piggies will sink or swim based on quality. If it’s a hit, Rovio will establish itself as the best — if not the biggest — mobile game maker in the market.
