If tu play Angry Birds Chrome, the past 60 days o so have been absolutely outstanding. Today’s update marks the third update in less than two months, and adds two — count them: TWO — episodes to Seasons! tu can now play both Trick o Treat and Mooncake Festival (the α and ω of the 2011 Seasons lineup, respectively).

Also included in this update is a direct link on the initial “Play” screen to Angry Birds friends on Facebook. A minor addition, but still notable, as Rovio continues to plug their facebook app.
