Just the other day we pointed out (or were moaning about) how Angry Birds was missing about 105 levels from the v1.0 release. That's due to our port being based on an older release (v1.4.2) whereas the iPhone and Android are on v1.6.1. Basically Rovio is known to frequently update the app on the other platforms, adding new levels and making the financial investment (if there was one) quite lasting--in fact it's one of the reasons people keep playing the darn game.
Good new for us is that v1.1 of Angry Birds is now live and now features 225 levels, up from the previous 135. What that translates to is the addition of Episodes 10 and 11, which were previously locked with a "coming soon" on them. This translates to the "Ham 'em High" or section 5 in the game. In addition, as can be seen by the lead pic, the design of the game has changed a bit too, but nothing that should get anyone upset.
Hey, for $2.99 and after being out for a few weeks, kudos to Rovio/MSG for pushing this update just as many of us were finishing those 135 previous levels. Hopefully we'll continue to see this trend with this game as it progresses.
