Rovio has just released an Angry Birds spin-off called Seasons. According to an email they sent out this morning:
Today, we bring you Angry Birds Seasons, a special edition spin-off of Angry Birds!
Season’s Greedings consists of 25 daily surprises for fans of Angry Birds to enjoy while counting down the days until Christmas.
Included in the game is also the 45-level Halloween special edition, now packaged as a separate episode called Trick Or Treat.
Angry Birds Seasons is available for Android devices through GetJar and Android Market.
This new version is a free 12Mb download. We'll give you some screen shots after the break.
A new Christmas level will be made available each day between now and Christmas Day. The Halloween levels are available for play immediately as you complete each one in succession, as with the original Angry Birds.
From what I've seen so far, the new levels look like a load of fun.
Rovio also noted in their email that they are still working on a "graphically lighter" version of the game to the Market so those with phones that can't quite handle the existing Angry Birds will be able to join in on the fun. They are also still working on a payment system that will provide a means to get rid of those annoying advertisements that love to get in the way of the game play.
As promised, here are some screen shots of the new Seasons edition:
