Angry Birds Space, trailer above, which offers revised physics and gameplay to the time-tested time suck, is out today! Forbes says it’s a key launch for Rovio:

But the formula has begun to show its age, and Chinese Lunar Festival levels start to look an awful lot like Western levels, start to look like St. Patrick’s Day. Rio worked as a tie-in with a movie, but it was the same game.

Which is why the casual gaming world is eagerly downloading Rovio’s new Angry Birds: Space to see if Rovio can keep its name synonymous with mobile dominance. It promises not just new birds and cute little masks for the existing ones, but a revamped physics engine with shifting gravity focused around asteroids and planets rather than one consistent force.

Physics was never our strong point, so we’ll rely on our strong forefinger.
