Three games from relatively recent reviews have all received robust updates of late. Forgive me if these aren't exactly "new," but if you passed on these games in the past due to concerns about content, take note: now's the time to try them again.
Clickgamer's Angry Birds won my heart with its quirky style and cheerful, bizarre art. One feature that was notably absent from the birds-in-a-slingshot game, however, was online high scores. The 1.2 update remedied that with Crystal integration, which brings leaderboards and achievements. It also included 42 new levels for an already-great game.
Rafter is a great physics game, and a simple one: you draw rectangles and circles in the upper area in hopes of them colliding with the red target below. In my review, I noted that while the puzzles were challenging, inventive, and fun, thirty-one levels just didn't feel like enough. Apparently in response to such complaints, the developers have added another 10 levels, bringing the grand total to 41. It's a free update, and one that leaves me much more satisfied with Rafter's length. I already loved Rafter; now, it's even better. More content is always a good thing!
Back when I looked at Doodle Bomb, I just didn't find it challenging enough, and it took too long to reach the harder "master" levels. The app has since been updated with additional levels—10 extra "master" missions and 5 normal levels— new physics devices like anti-gravity control, and the ability to jump straight into the hard levels. There's also a lite version if you were on the fence before. It's still not the most challenging physics game out there, but these new tweaks are nevertheless appreciated.
